Engine Performance problem
2009 Infinity G37 6 cyl Two Wheel Drive Automatic 1700 miles
This isn't a repair question. I a recently purchased a G37 convertible and am looking into putting a supercharger on it. It is made by Stillen. The major questions I have are, first, can I count on anyone other than a dealer to install it reliably (including adjusting/reprogramming the vehicle), and second, will it have any negative effects on engine life? This is assuming, of course, that I don't drive the crap out of it, which I definitely won't. But the HP boost would be nice from time to time.
The supercharger is made by Stillen, so if you have any opinions on that brand as opposed to others, I'm all ears.
