Can someone with an AEROFORCE or other datalogging unit please tell me how long it takes for your fuel trims to reach 0.0 on decel? I know mopar programs the staged computers to delay injector cut-off, I'm wanting to know how long it takes your STG3!

I have ported exhaust, intake, and tb and my LTFTs are 3.1 at idle. STFTs are around 0.0 to -1.1 or so at idle. Next time I drive it, I'll watch the FTs to see how long. I would suspect about 1 or 2 seconds based off the values displayed on my wide band. (Goes rich, then lean after 2 or so seconds upon decel)

ie. max lean that your wideband can monitor? I'm having an issue where my injectors aren't shutting off on decel, bad bad bad

Both conditions are around 14.5 or right around there.

Installed stg 3 a couple weeks ago. I'm using the stock stg 3 WG. I have the AGP Stg 3 WG but I have not installed it yet. The WG looks to be as tight as it will go but I can not boost any higher than 20 psi. And boost is the same in Dab2 as it is in Dab3. Other locals are spiking 23 or so on the mopar stg3 WG. I have zero boost leaks and the WG is hooked up like stock. Any ideas why it won't spike higher, and Dab2 is the same as Dab3 ?

The WGA needs to be adjusted all the way, I had to pull mine over the exhaust manifold stud, but I still boosted ~20psi but spooled quick! I had to go "manual" boost controller to get any higher, and lost all DAB functions. Either way, the car is smarter than you when it comes to these things and when I messed with it, I couldn't get it to go back to stock.

Point being more boost doesn't mean faster, but when I was pushing 28lbs it was definatly faster!

It is adjusted all the way. I can't figure out why it won't boost any higher in dab3 than it does in dab2.

I thought dab2 was gay, seemed to help on the 60' times, but otherwise very similar to dab3. I think when you play with the dab enough, you will get bored like everyone else and just roll in dab3.

When your ready for more power, just install that agp wga with a boost controller and start hiting that 25-29 falling off to ~20 at redline, but pain to get dialed right, cause then you won't be spooling as fast as you are now. Then you get that HOM all set up nice, and you will have exceeded the stock clutch capacity.

Why you posting here? You have more than enough resources in PacNw. Froggy, Back in Black etc. I wish I was there that day for your install, I wanted to see the toy box wired up.

Yeah, Frog & BnB are great sources. But they have already helped me so much I just didn't want to bug them again so soon. And Frog is not running toys on his ride, so I wanted to see if someone that was using the Toybox could tell me if they were also boosting the same in Dab3 as they were in Dab2.

And if your running the AGP stg3 WG is a boost controller necessary ? I thought you could just adjust the wastegate to control the boost ?

would it be possible to just upgrade the spring on the stage 3 wastegate instead of getting the entire agp unit? just wondering because I know pt performance sells an upgraded spring for the stock wga but I havent seen any for the stage 3 one.

DAB 2 & 3 are the same except in 1st & 2nd. DAB 2 gives you less bosst in 1st & 2nd for help getting traction from a dig. 3rd & 4th gear are the same....usually.

THat being said, I think I need a new solinoid. All of a sudden my DAB 0 boosts the same as DAB 3, but without the fuel to support it. I am wondering if my solinoid is stuck & letting the actuator get all the boost refferece DAB 3 allows. DAB3 is fine & stays rich like normal, but DAB 0 hits 20psi & A/F skyrockets. Ugghhh.

Anyone ever see anything like this?

Your fuel pressure is a mechanical rising rate. DAB shouldnt dictate how lean you run...
