Is it because I need a tune?
Basically, the Mods are: Kooks headers, GmmG catback, march underdrive pulley. Is that enough to through the stock tune out of wack?
There are good tuners and shops out there. But, don't assume they all are decent. The other option you have is to spend a little more and get your own software. There are people that will help you here if you can't get past what's spelled out in the instructional files in the stickies.
