Hi all. I just thought I'd share my recent experience with the Superchips Flashpaq programmer.

Like some others have already posted here, the Flashpaq didn't do anything worthwhile for my Hemi. I tried the 87 Octane and Mileage XS programs (I'm not interested in the 91 Octane program). In both cases not only was my mileage worse, but I wasn't happy with the way the transmission was shifting. It felt like either it was easily slipping in to / out of gear, or perhaps the torque converter was locking / unlocking frequently. It felt weird, so now I'm back to the stock program.

So I'm wondering if my experience is typical for Hemi owners. Do those of you with the 4.7L have a different experience? Maybe someone has used this programmer on the 3.8L Wrangler?

Has anybody used the programmer for anything else other than tire size changes?
