Is any one running the ZZP PCM? If so, please post your dyno numbers if you have it and what is your A/F?

 

I am also, interested to know how these pre-programmed PCM's are working out. They look like a good idea for a fairly cheap price

 

runs great very highly recommended my #s are in sig and dont be fooled by them i am at 2500 alt 85 deg i was running a 2.8 and still because the air is so thin i only make 15-15.5 lbs boost and a/f was perfect at 11.5-12.0 the whole rpm range in 4th gear with 42s everyone claims they go crazy at 6k at the top of third... so i trust zzp 100% they have never done me wrong and there tech serv is GREAT

 

When I contacted them thats what the A/F would be at...and Iam thinking its too lean. I do trust zzp but at the same time I dont what to blown my engine.

 

FYI, with an Air/Fuel Ratio of between 11.5-12.0 you will be right where you want to be on any Forced Air Induction engine tuned properly. Less than 11.5 you will be a little to Rich. With more than 12.0 you will definitely be a little to Lean , especially running over 15 psi of boost. Actually 11.5 to 11.8 is the sweet spot for performance running higher boost numbers. Hope this helps.

 

Hey thanks alot...Btw u guys make great pulleys.
