Re: Diablo - HemiFever Tuning - Question?
^^ X2. I've run both of the hemifever tunes I have- 89 and 91, and love, love, love the way the jeep drives now. Night and day difference from stock and also the diablo canned tunes. Not seeing the dramatic increase in MPG some others have shared, but may be because I can't stop getting after it from time to time. When I have tried to drive it normally like I did before the tunes, I'm definitely not seeing worse MPG, and it actually looks to be a little better. As others have said, this is MUST have for the WK2.
