Have a 2009 cobalt ss turbo (victory red) installed zzp fmic, silicone couplers, upper and lower zzp charge pipes, 200 cell catted zzp downpipe, k&n sri, and just got the zzp PCM tuned to 25psi!! The car is real quick!!!! Any upgrades left? Any easy upgrades to get a little more?

 

Unless you have access to biofuel (E85) in your area the only way you'll get more power is with a bigger turbo.

 

hell yes, cant wait e85 here i come!

 

E47 or you could get cams and run full E85. You can always get a bigger turbo too.

 

I want the zrf zzp turbo but I need a lot of things before my car will support that! Injectors new clutch possible head or block (what I've been told) and about 4 sets of tires hahah

 

How did you get the pcm tuned to 25psi? Did you take your car to zzp?
