word... stage 2's prolly good up to 19ishpsi... (verify your a/f's w/a wideband cuz i dunno for sure)...
a walbro will help you a lot... do the re-wire while your at it...
cheers
Yeah im looking at that, or also looking at the bottle neck fix. I read that people not having good results with S2, but imma play with it see what i can get. I will be buying a wideband and i'll make sure i have it once i start turning up the boost. I was looking at the NGK, looks like a good model.

hows the lag on the 20G and when do you have full boost? Im debating picking on of these up. and the price between the 16-20 isnt to drastic. The 16G is to close to stock size for me though.
and I allready have all fuel mods, i would just need to buy a DCR clutch

Went to the dyno today. Not the greatest number but I put down 334 hp and 354 wtq @ 22 psi. That was on 111 Octane. (Yeah I know) Anyways, on pump 93 the numbers were down just a bit 330 whp and 34X tq.
This was on Hahn's base tune. Anyone know what Map A and Map B are for? Do they both control the Additional Injectors? Or does Map A control the first two and Map B the last two? I'm just trying to figure this thing out to keep from blowing something up.
Also, I have the AEM wideband placed right before the cat (ED 3" duals with Cat). Now, my wideband showed 10.0 AFRs in the upper RPM range, however the dyno wideband showed mid 13's and higher. That is why I didn't crank the boost up any higher. I really wasn't sure WTF was going on here. I was too busy using the R4 Controller to notice which tailpipe he placed the sensor in. Either way I am now highly suspicious of the AEM wideband and the stock tune.
Well, any input is appreciated. I wish I had more time to solve all the issues and crank out 400 whp. Being in the military sucks at times.
Map A and Map B MUST be identical. I haven't really figured out what they exactly mean but at first I thought map B was just a backup. Like if you wanted to make a race gas map and have a pump gas map. But as soon as I cleared map B and only flashed map A my car as lean as hell. Copied map B to map A and it was all better.
My wideband is saying 10.7 to redline on the base tune + 5% all the way around. I'm really hoping that the AFR the dyno guys read was wrong or else we are all in trouble.
You numbers did seem pretty low compared to some of the other people here. I have had a lot of trouble with a leaky manifold and leaky injector O-rings. Replaced the manifold gasket and O-rings (cost like $9 for everything) and my problems were solved.
Hey, how high do your portfueler maps go as far as boost is concerned? Mine only goes to 26psi, and I've heard some people have maps that go as high as 30....wtf???
Ok...I think that was my problem. Map A and Map B were not identical.
I'm still trying to work out why my AEM showed a completely different AFR than the Dyno's wideband.
Oh yeah, I noticed that the Portfueler tuning only goes up to 26psi as well.
Yeah, better be careful..I melted my #1 piston because I had different maps...just copy and paste from A to B whenever you make a change...
Is everbody else's maps limited to 26lbs.?? I could've sworn I've seen folks talking about have 30psi maps, and I know someone who said his buddies 20G maps go to 27.5...I need to get higher than 26...hopefully 30 or more.
There is no point in going past 26lbs. Mine only goes to 26lbs. The 16g and 20g are way out of their efficiency range above 26lbs. Get a bigger turbo before you try and run 26+lbs.

Ummmm...I HAVE a bigger turbo so I have DO a reason to want to go past 26psi. I'd like to get the most out of my GT3076R...and before anyone gets pissy, I have a Super20G kit from the first batch Hahn shipped out when it was released...I just had to go a little bigger. Great kit, gonna put it on my wifes car,and yes, 26psi will be enough for her...I hope.
Looks like I might have to go the friggin return line/emanage route again...

Damn, don't get so defensive. Bigger turbo doesn't always mean higher PSI. You want to think in terms of CFM. That is a nice turbo, a local guy made 380 at 20lbs on that turbo so good luck. But like I said, a big turbo will have more CFM and more PSI does not always equal more power.

Hahahaha...not defensive at all. I appreciate the concern and I understand that more psi doesnt necessarily equate to more hp, but in my case I have already been to the dyno and put down 442whp and 456wtq @26psi. These turbos are good to 33psi, and I want to use it to it's potential, the motor is gonna be built to take advantage of the increased airflow. The only limiting factor for me is the fuel map of the portfueler and the 26lb map. I have the turbo and the fuel system(RC 650's instead of the 500's it comes with), but without the map going to a higher scale I'm dead in the water so I'm trying to see if I have any way of keeping the p-fueler because it is a truly awesome setup. I think I'll call Hahn, maybe they have a 25G map the has the higher scale UNLESS someone can help me out with something higher than the 26lb maps.
Yeah even before I dyno'd I had been thinking going with a bigger turbo. The S20G is really great for every day driving and reliability. It sure was great beating that 04 Cobra with mods.
, W/M, Custom 3" O2 Housing and some other goodies.
