Well got my UEGO gauge and zzp tensinor installed last night and did a few run's tonight..car pulls harder with the adjustable tensinor,also i decided to put the s2 pulley on since my 2.9 got damaged when my buddy was taken it off,so its kinda messed up...anyways..2nd gear afr is 11.3-11.6 and 3rd,4th,5th 10.4-10.7...car run's rich top end even at 130+..so a 2.85" on s2 tune would lean it out on top end,and wont be maxing out injectors..weather is about 30ish degress

 

u have ur tune?

 

no tune...still on gm s2 tune..

 

thats akward..

 

why?

im not suppose to be running rich?

 

well u should be getting leaner

 

nop..regular driving and idlin its a 14.8-15.4...and WOT the faster i go it starts to run richer..im guessin that a sign for a smaller pulley and bottle fun

 

so ur not on a 2.85 then?

 

WAS until my friend cracked the pulley,luckly had the s2 in the glove box

 

lol i dont think i am understanding the question then

 

the question is why am i running rich with a s2 pulley on im still on s2 tune.

..2nd gear afr is 11.3-11.6 and 3rd,4th,5th 10.4-10.7...car run's rich top end

 

try cleaning ur MAF

 

from what ive heard, thats about normal on a stage 2 reflash. most tuners shoot for 11.5 under boost. gm riches it up further to help controll combustion chamber temps under long hard throttle pulls like you see in 3rd 4th and 5th.

 

so thats a sign that a smaller pulley than the s2 will help lean out the car,and boost more power

 

11.5-12.0 is normal. make sure your wideband is reading correctly. 11.5 is where you want to be. Dont be to lean though and ruin your motor.

 

only reason i got the gauge is cuz cars been to dealer 5-6 times and they keep tellin me cars running lean (p0171)..so i got pissed off and tired of all the b/s and went and bout a uego gauge,and looks like its the opposite,plus rich is better than lean..

 

Gauge might be off. If you get a guage the dealer will now revoke your warranty haha..... Gay ass gm.

 

i have 1k left on warranty,so im not really worried bout that anymore..lol

 

Ya **** GM..... They want you to buy there 20k dollar car then they revoke your warranty..... Piece of **** company,

 

that piece of **** is number 1 in the world...lol

 

every car is different....thats the problem with this "universal tune" bs. Your afrs aren't going to be the same for everyone with the same tune.

 

thats wat i always beleive..not every car is the same..even if tunes are really identical,one car will run diffrent

 

Based on everyones cars are stage 2 only, GM made the tune generic. They made it to be a little rich for safety purposes. They took into consideration temp, elevation, and climate. They know that everyone that will be purchasing the stage 2 kits live in different climates. Yes, the tune can be made custom to make your car run better, but that is totally up to you. the stage 2 tune had to be generic for everyone so the warranty could be kept.

 

Yeah until you clog your cat from running too rich.Theres a software update to fix the P0171 code.Did you get it done yet?

 

That is when you gut the cat.
