Hey every one i jsut got my 5/8 plenum in today and plan on installing shortly. Right now i have very basic mods on my car in the plenum and JWT Pop charger with z-tube. So here is my question. Which chip if any will give me the best gain of HP at the wheel. Im trying to get the most possible hp gain without going with FI, and im not looking to change the exhaust at all.

 

There aren't any chips for these cars. You can either send off your ecu to aam, uprev, or technosquare to have it reprogrammed (about $500-$600 I believe), or you can get an engine management system (Greddy Emange Basic or Ultimate, Utec, etc.) that can cost anywhere from $400 and up.

Do some searching and you'll get more info than what I can give here.

 

or wait for COBB tuning
