For those that have Maggie superchargers...

I actually did a mail order tune on this one and the last one--the superchips tune is every bit as good on the H2 except perhaps a little better shifting performance with the ordered tune. I do believe you could send your programmer to Magnusun and have them reprogram it for a small fee. It's still a 6500lb pig, so nominal hp gains are probably not worth the $$ and effort. I would use the superchips tune, forget the dyno, and maybe toss on some headers. You could do a water/alky injection system to cool the intake temps, but again, small gains. On the H2, I even had Mag set up the tune for 87 octane fuel and it still puts out 7-7.5 psi with no detonation at all--gotta be happy with that!!
