so i have vibrant headerback exhaust and injen cold air intake and i think its about time to get some stage work done, what would be better the gm stage 2 or the zzp stage 3 or 4 also what do i need to run the zzp's, also if anyone lives near dallas can you tell me where i can get a tune cause you need one for zzp's right?

 

no zzp's is good but its also a little rich which isnt such a bad thing....an you cant beat a price of 625 shipped w/o the core charge for the stage 4...stage 3 is a total of 500 shipped w/o the core charge and of course i figured em like that cuz i sent my pcm to them to get tuned then they flashed it an sent it back...only problem is i'm the unique one an somehow my gas gauge is f'd up....but i believe i'm the only one like that an they are looking into fixing it for me

 

how big of diffrence in power is there between stock and the stage 3?

 

its about the equivalent of a stage 2 from gm but i got it tuned for everything i have an including the header/dp i'm gettin from them which isnt installed yet which would be why i'm running rich....they will tune you for the mods you have, CAI and exhaust an wat kit you get from them.....big difference in power tho..verry happy
