Ok so I bought an 08 GTS with cvt ( got tired of driving stick in the city). So from what I've seen turbo isn't really an option right now. I bought the RRM timing module and I'm thinking about the ecu piggyback. Does anyone have a # for how much HP the ecu piggyback adds? I have a CAI and I'm slapping on a cat back with tax returns. Any other suggestions on what I could do? Thanks.

 

You could get a RRM lightweight pulley, that frees up some rotational mass and improves response. If you already have a CAI and your getting a Cat Back exhaust, the RRM headers should improve your Horse power, (Depends on what exhaust you get tho, I heard it sounds bad with the injen exhaust)

 

from what i remember the piggyback does like 9whp
