I have stage 2 no toys on my car. I have my wga adjusted but i am only holding about 15psi with no boost leak. anyway i want to know what direction and how much should i tune it so that i can make it hold more boost. i currently have it set at teh 4mm preload. do i want thread it in more towards the drivers side or thread it out more towards the passenger wheel? i do know that evertime i make an adjustment to reset teh ECU adn go do a 4th gear pull to let teh ECU learn the setting. and info would be much appreciated!

 

without good fuel mods you won't hold much more than 15 or 16.I suggest you buy a wideband and go from there on to more important stuff, like return line,fuel rail,pump,injectors and a good tuning device

 

I hold 17 and 18 after spiking 20 so you dont need fuel mods if you already have stage2 without toys like me, mess with the preload again till you get it right, even if you do have it at 4 mm preload.

good luck and really make sure you have no boost leak

 

Well like red said, if anything u should get a wideband when messing with the boost. I dunno how muchthe s2 wgaholds but you can try buying the AGP or Forward Motion wga's that hold a lot more to redline.

 

s2 runs pig rich so i don't think you'll have much of a problem running lean lol. get a wideband just to be on the safe side though, you never do know.

tighten the wga up some and see how that works. you can hold more than 15psi on a s2. also look into some w/i, s2 loves it!

 

I was holding 18psi on stage 2 with AFR's in the 10.5's

 

haha yea, pig rich!!! also kills gas mileage, fuel control is a must on s2.

 

Gas mileage was WAY bad ..... Last tank on the 50 Trim I got 21mpg.......with just S2 I was getting like 15!!

 

Is it that bad? I will be tuning like crazy.

 

a lot of people say they have bad MPG, i really dont maybe all my supporting mods help such as....
MPX Full 3 inch Turbo back NO Cat
Mopar Intake
FBM Ported TB& Spacer, Turbo, With both Manifolds
Built head wth older 2.0 cams
Spearco BIG FMIC with JMB Pipes
Mopar BLue Plate (lol i love truck brakes and i havent had a problem with a boost leak)
180 t-stat
Avid Mounts with tranny (still have wheel hop so now i am switchign to Boomba) any one else have this problem with these?
tracklites all around with 15's for my slicks
my best run so far with S2 with slicks on the track was 12.5 and soon i will be going big turbo anyone else got any suggestions
