If your gonna get a handheld tuner and use the performance tune it has, then you should get it dynotuned also. The tuner will get your engine in synch with the mods you have. If you've got a Catback, midpipe, and CAI, then I'd get the tuner. You'll gain about 12RWHP and TQ after the dynotune. Not sure what you'll gain with the initial "can" tune. Plus the tuner has quite afew other functions you can use. Pull codes, gear changes, traction control delete, 02 sensors, and some other stuff.
We'll don't get pullies because you'll be pulling them off once you buy the supercharger.
I would get an SCT Xcal2 but it's really whatever your tuner uses, most use the Xcal2 or the Diablo.
An SCT and Diablo both cost about $300.
how do i know who my tuner is...??? should i go to a local performance shop???
thanks for the out put
