I found these two Stage kits.. and can't really tell much of a difference.. Can someone explain the difference in these two, AND tell me the Horsepower gains from each.
(If I were to get the OTTP kit, i'd get the h/e also)
I have the 07 cobalt ss/sc If that helps..


OTTP Stage 2 kit

OTT Stage 2 Kit - Over The Top Performance


ZZP Stage 3 Kit

Cobalt & Ion ---> ZZ Performance


Thank you.

 

there is really no difference.... the hp will be about the same, but that all depends on the tune.... u will have to get tuned after the install even if u send ur pcm.... custom tuneing will get the most out of u car and the ( can ) tune are usually pig rich...

 

the search buttom is ur friend use it and learn

 

Thank you, metalmedic.
