t1000 custom tune issues

hey SRT forum family,

Long time srt guy here, but i could really use some help troubleshooting my Diablo T1000 issues.

After working with a "reputable tuner" through email for the last few months, I finally got the car to where I felt it was running good.
11.4 afrs across the board, with what my tuner called "big turbo timing and no detonation"
24 psi on 94 octane.

anyways, i went to pull some boost the other day and the t1000 lost my tune and reverted back to stock.
not an issue, loaded up my last custom tune and started tweaking.
i got it close and again the handheld loses the tune and reverts back to stock.

i flash the custom tune back on the t1000 and this is where the problems start.

boost control:
-39 will give me an uncontrolled boost, as if the WGA has no boost reference. it spikes uncontrollably. even when the car is cold.
-40 will bring the boost pressure down to spring pressure "7-10psi" it will not spike more ever.

mechanically,
unhooking the boost source from the wga produces the same effect as -39
running the WGA straight off the turbo will produce 7-10psi, or spring pressure.
i have tried swapping out the wga solenoid, the extra produced the same result.

i have triple-checked all vac lines and nothing is cracked or split, factory routing. it worked great up until this issue.

I called diablo and they said i need to have the "unique vin" that was on a faded sticker on the back of a unit or they cant access the handheld to troubleshoot anything and that even if they could, its been 6 years since they have updated the t1000.

has anyone experienced anything like this before? i have been debating buying a stand-alone for awhile and i really dont want to drop money on newer diablo products if it is my PCM that is the issue.

i, unfortunately, do not have an extra PCM or handheld to try.

any help or insight is appreciated, still waiting to hear back from my tuner on if my tune will work on a new handheld.

i dont remember the exact issue i had, but with my t1000 i believe it was i couldnt load tunes from the tuner onto the car but i could put them on the tuner from the computer.
i contacted holley (diablosport) and they gave me a discount on a new tuner of my choosing with me sending my t1000 to them.
ended up upgrading to a T2 and its way more fancy than a neon requires lol. think it was like 30% off or something cuz it was like 400$ or so off regular list price with the extras i got.

not sure on the whole turning boost up and down with it tho... that sounds like a canned tune deal not a custom email tune.
the tune was fine before the issues, i can try loading one of my earlier revisions “i have 12” and the boost still goes out of wack.

the handheld successfully loads the tune, it just doesent effect the boost curve properly anymore.

I honestly think its the pcm or some sort of data sector corruption at this point.

i bit the bullet and im giving up electronic boost control and going with a AGP stage 3 WGA .
I grew up on that WGA a little ptb dont scare me.

I however Cannot bring myself to bug duster or replace the unit incase its a pcm issue as i dont wanna be out close to 1500$ cad and back to square one.
Hoping something fails, besides the stock clutch that just started arguing in the higher RPMs while tuning last night 🤣
Ps duster is not my tuner, he is just who i wish i would have went with as i was told/recommended a AGP WGA on revision 2 through my tuner as apparently

“The pcm boost control causes everyone problems”

which i think has been proven to be utter trash and an excuse from my tuner to not dig deeper.

So if you know that it's utter trash and just an excuse because you know better, why do you need the tuner to tune your car?

Also a "stage 3 wga" is for the stage 3 turbo from Mopar, it won't fit on stock turbo if that's what you have. Might help to list some mods if any you have.
I think he has a stage 3 based on his username.

Where abouts in Canada are you? Chris at Player3 performance is in Edmonton and is one of the best tuners for these cars that most have not heard of. He also works with shops remotely if you're not close.

Because i had already paid for a canned tune and im not gonna insult the guy emailing me tunes, mid tuning. pretty self explanatory scenario.I needed a CMR for a rescale i have a stock pcm.

i have a stage 3 car.
Nothing you said is contributing or helping me.

This is a Dsport workgroup. My mods are not pertinent unless you are a noob.
I have confirmed them to be mechanically functioning correctly.

people like you are why i left this forum 10 years ago and diddnt wanna sign up again , just a fyi.

I am from lethbridge and i JUST herd about this guy yesterday in fb.
The neon community has always been toxic so i was hesitant to reach out . Sorry not sorry.

is he a CMR ?

i mean sure go for the 6-7k+$ option when a 2-300$ or even less fix is probably all you need...

and also nothing you have said states that your tuner is wrong, you just posted here saying hes wrong with next to no evidence to prove so.
not saying there arent incompetent tuners but im not one to blindly toss someone under the bus. ahem fueled by matt cough*

have you ever thought that something like your wga had failed? like the diaphrgam inside had ruptured and not working properly?

i have a oem pcm with a CUSTOM email tune running a built bottom end big turbo car thats got a external wastegate and my boost control is on a "standalone" boost controller (n2mb) and it works fine.
i cannot modify my email tune on my T2 and because the boost controller is a separate system aka stand alone it cant be changed on the trinity either

Oh, we aren't nearly as bad as we used to be ;)

i would love for this to be a 2-300$ fix. the stand alone option is a last resort if I cant get the diablo tune to work as intended.
the stage 3 WGA i ordered fixed my boost control issues at the expense of drivability.
this has unfortunately highlighted other issues within the tune now.

for reference, here are a couple things the tuner told me via email that support me questioning his abilities or at least his efforts.
-everyone has problems with pcm controlled boost, get a wga and that will go away
-getting a AGP wga will smooth out your tune and solve a lot of your problems
-i assumed your turbo was crap the whole time
- your stage 2/3 injectors are running like stage 1s
-its got to be your brand new MP fuel pump
-get our bigger injectors and it will solve all your problems
-all the issues are gone now, everything is fine.
-i forgot to add that to the tune, here try this one

this is just some of the stuff that stick out off the top of my head, I think he thought i was new to the car?
a lot of what he was saying has 100% been proven to be wrong.
The suggestion to ditch pcm boost control came super early in the tuning process and was an immediate red flag to me, but i was already invested.

when i tried to trouble shoot my issues with them, the tuner would always blame something else.
when i asked about adjustments on certain settings he said he just cranked them all to 980, probably why i needed -40% to control boost.

Tuner has since told me to find someone else to tune my car 🤷‍♂️.

now that i am on WGA controlled boost i am seeing alot faster spool.

this has caused a new issue with my tune, 3600-3999rpms my timing shoots up 8 degrees causing like 6 degrees of detonation, even with the handheld at -10 for the range.
my IDC also tanks at the same time the timing spikes.
Adding fuel to the range seemingly only effects 3000-3500rpms
cannot pull anymore WOT timing from the tune. 3-4000 is at -10 , MBT is at -4
AFRS are hitting 13.0 during this event and my plugs are as white as a ghost.
afrs are good everywhere else, a bit lean up top but like 11.7 lean not blow your shit up lean.

none of my inputs change, iat, throttle Voltage, boost, it all stays the same. timing just randomly spikes.

For the record my fuels system is

Stock FPR
Walbro 255
Stage 2/3 inj
Stock fuel rail " i have a stage 3 rail but was told not to install because of stock FPR"

Tuner said it would be plenty of fuel for a pump gas tune before we started, but we wont talk about my overall duty cycles unless we have to.

here is a image of my log for reference . any help is always appreciated

Tune is -10wot for that knocking range and mbt is -4

Go see Chris in Edmonton. It will be worth the drive.
Hit up a reputable tuner. You can't fix a bad custom tune with the diablo sliders.

Wait, he recommended the AGP WGA rather than the Stage 3 WGA to use with your setup? I thought the Stage 3 WGA was the optimum setup for the Stage 3 turbo kit? Assuming that's what you have based on your user name.

It is, the agp wga was only usefull back when we “the community” had no electronic way of modulating boost. The dsport made the agp wga obsolete.
this was the tuners way of avoiding pcm controlled boost , alot easier to just write fuel and timing.

The company i went with was big enough thag i thought they would know what they were doing, hell they specialize in turbos, but now i know i should have went with duster.

Still waiting to hear if he is a CMR tuner. If hes not its not worth my time lol sorry not sorry.

I rolled the tune back to a previous revision and it fixed all of my issues . The tuner must have done something on the last tune, probably why he turned me away when i said it gave me problems

He tunes with HP tuners, much better option than CMR these days. You dont need a handheld, he provides. I still used my Diablo as a heads up display with his tune before I went stage 3.

He tunes for Ricardo/Full Throttle Fab in Florida, about as reputable as you're gonna get.

Are you holding out for CMR because you have the software, so you can make changes? Otherwise there's nothing CMR can do that HP cannot....and HP provides the software for free.

naa im holding out because i already have the diablo handheld and i want to know what the main issue is before i start changing to much stuff. Be it the hand held or the tune or whatever.

prior to losing pcm boost control, the car was running pretty good and now even on the agp wga and a previous revision, its running pretty good again. Ptb isant even bad on the stage 3.

we have a major car event coming in western canada here in a month i bet he comes down for it if hes a bug car guy, i will try and find a way to reach out.
