yea my stage 2 injectors are at 119% duty cycle on the stage 2 tune, and stage 2 pulley. thanks GM.

anyone got a set of 60's and a harness i can buy?

 

wow ..good old gm

 

i had this realization 4 months ago. a good tune will lower that IDC some but you still are gonna be at 100% on the stage 2 pulley. all of the stage 2 cars are like this.

...how people get away with smaller pulleys on the stage 2 injectors/tune is a mystery.

 

to bad we couldnt take somekinda action against gm for **** they throw together

 

****, this sucks

 

if i had known then what i know now....
gm stage kits are WEAK SAUCE. i wish i didnt waste my money on it. for the same price or less i coulda bought injectors, pulley, and tuning.

well, i'll clarify my comment. the stage 2 is a decent gain for someone who has warranty issues or doesnt want to mess with their vehicle. but for the rest of us, aftermarket FTW

 

damn 120%? lol thats fucked up

 

ive always kinda had the feeling that IDC isnt being properly calculated for us.

because look at how many people run/ran 2.8s for a LONG time now.
and there has not been a single popped engine from it so far.

something just doesnt add up, ya know?

 

^^ i agree. i know people running 2.8's and 2.9's for years and been completly fine. i thik they can do more, and i believe they are rated at around 310hp....not sure though

 

^^ i agree

 

?????
damn, I wonder what my IDC is when I Spray?????????????

 

well with that being said, im certain a 2.8 is pushing it....because i could distinctly feel my car falling on its face after 6500rpms, and when i went to 60s that was completely gone.

but yeah. somethins gotta be off.

 

lol thats hwy i think tis rated higher...otherwise why would that make a stage 3 with a smaller pulley and 50 shot if the stage 2 is at 120

 

did you need a tune when you went to the 60 lb injectors? or does it matter?

 

yea but you wanna see some data logs from tonight? scary ****

 

I have plenty that look the same hehe.
128 was my best

 

did your AFR ever rocket to 18.8 at 6 grand in 3rd?

 

err....no
lol

thats big bada boom....

 

is a tunre requierd with 60 lb. injectors?

 

ha yea im thinking somethings up

 

yes a tune is needed

 

yes, you have to tune new injectors, they are not plug and play.

 

Im going to finally dyno my car within a week or so. I really want to see what the A/F ratio looks like.. Everytime I spray, it runs fine. I just raced a BMW Z4 M3 last night and took him by 3 cars on a 2nd gear 30mph roll. We shutdown at 120mph. The car pulled very hard all the way, engine temp was at 185. It only went up 5 degrees.

But I really have to get it dynoed. Your numbers are starting to worry me.....................

 

i want to know your stage 3 numbers!!! im thinking about picking up the pcm... i have everythign else

 

if your throwing 60's in might as well pulley down
