My gas mileage is 21mpg. in 6th crusin' with 2,000 rpm's. Around town if I'm drivin' nice I get about 14mpg.... although that's rare. It's usually less. Get the gear and get Bryan Herter @ pcmforless to give you a tune and I would think you'll be gettin' that kick you so desire. Yes, he can tune it before you install the gear. I can't vouch for the 4.56 with a supercharger... Mike has a good point about maybe asking 2005SSR6SPEED about that gear and s/c combo, although I believe Jim Gnitecki is running 4.56 supercharged. Send them both a pm and see what they say...

And so far as tire spin, I've learned to not dump the clutch at 6,500 rpms... at least not after I've driven through the water pit...

BTW... How's your clutch?

It's still good after 12K - plus miles so far...
