i kinda thought that was a bit high because of me being untuned

 

damn man .1 pulley drop, intake and cat back netted you 20 hp
i dynoed (Same dyno) 226/200 with just 3.0", 42#, airbox mod and tune

 

how are the air fuel ratios with gm stage 2 and 2.9??
I think this is the route im taking in the future.

 

if you look closely, you can see the afr on my dyno sheet. it's labeled 11.something at one point to give you an idea. it starts to lean out top end

 

11.72 is what it says I believe.

 

Wow thats nice guys i always wanted to know what you guys dyned also with the 2.9 pully

 

what the hell do you use to get the stage two pulley off???? they are some weird looking star shaped bolts or something

 

Here is what mine dynoed at. Thought it would be a more but not to be bad on the gm stage 2 tune.

 

can't see the sheet, it''s to little

 

Yeah give me a minute to try an resize it again.

 

hey guys, I was going to start a thred anyway. so not to thred jack, but with my mods. (there in my sig.) and a 2.8 with a good tune and 60's should i be safe? remember i have N2O. also would i need a new tensioner?

 

Well I am running a 2.85" pulley, I dyno'd 262 and 237 hp... But injectors start getting pissed at you!

My mods on tha run were: Stg.2, 2.85, K&N Intake, Custom Ported Manifold, 3"-2.5" ZZP Downpipe, 2.5" Magnaflow Exhaust, and a tOoN by Area47, Conditions were 61*, like 20% hummidity!

The 2.85 generates more heat, so cooling mods are recommended, I didn't have any then, but I do now!

I'll get a new number once the new stuff is done which is, Water Injection and Cobra front mount H/E!

 

The tool that came with the gm stage 2 kit that the dealer was suppose to give back to you when they were done
