I installed a C&L CAI onto my 03 mach 1, and it also has a Bassani Catback on it. Do I have to have her tuned or am I fine with just what I got? I've heard both ways. Those are the only major mods that have been performance-wise done to the car so far. Eventually I plan to do more mods, but that's it for now.
No check engine light has come on....car seems to be running just fine. I was just wanting some more people to tell me what they think/or have experienced.
