I'm trying to figure out what to mod to get as much power out of this as i can. I already did a shift kit and tranny cooler, was the first things I did, lol. Like i said my budget is tight right now and not gonna do to much. Am I gonna be fine with those mods and not a tune or am i gonna have problems?
If you go the Diablo Intune Route, Definitely go with a LEW tune. Lewis does a great job as long as you data log correctly. You can always port your stock intake manifold if you have a dremel tool and polish and port your throttle body as well, if your mechanically inclined. Just make sure you do a little at a time and don't over do it, or you could see a loss in power and erratic idle. These are things you can do on a budget and make power without dropping a ton of money and make the feel of the car overall better. Shift kit as Blue said is a must for these cars! There is a sticky somewhere on how to make your own if your wallet is tight, and it works pretty good for what it is.









Not much money dropped, Looks good and a noticeable performance increase..... on a budget
