The flashpaq works great! It really helps the shifting of the transmission and gets up and goes a lot better. Can't tell a difference in fuel mileage.

I bought it hoping I'd get better MPG's by using the 89 tune, I don't really see a difference in fuel consumption, but it made a HUGE difference in power! I'm loving it!
