4.7 lifts with flash paq ?
i was wondering if any one would suggest to mess with any of the gear stuff with the tuner?

I have the flash paq but I have a WJ 4.7HO so I can't change the gear stuff. I think running the 91 performance octane setting is the way to go. If you start messing with the gearing and shift timing (RPM'S) you might mess up the overall performance and MPG. Just my 2cents.

yeah thats what i was thinking too. I tried running mpg tune for a bit and then I went back to 91 and I think that is definitely better then the mpg tune.

Contact the guy that the SRT8 boys use for custom tunes on the diablo tuner, he should be able to tell ya if there would be any benefits to messing with the gears cause hes a boss when it comes to tuning. Ill look for his name....
