I have a 2011 GT and I bought a Zex wet kit for a really good deal and would like to know whats a safe pill to play with without it doing major damege.. I have 125, 100, 75 and he used the 125 in his (also a 11 GT) so does everyone think the 125 is safe or should I go with a lower pill?? Thanks

 

I would start with the 75 shot and put it on a dyno and see where it is and tune from there. A few hundred bucks is worth it when compared to a new engine
