Flashpaq + 5.7L Hemi = not impressed

[Omelet]

Originally I was using mine when my only mods were a CAI and cat back. The three working together I could get 22mpg on the freeway. After the OME and 255s I could still consistently get 20 and at time 21mpg. I noticed a significant improvement in power too! Even after the lift and tires I could get up to speed faster than stock. It wasn't until the 295s went on that the power wasn't significant. Now with 35s the Hemi is still a beast only it struggles a little under 2000 RPMs. Any time I restore the tune back to stock I can't believe what a difference it makes. I am not sure why you guys are having such a hard time with it, but I hope you can get it figured out!

So far the three of us who are disappointed have 2007s. You have a first year 2005.

I'd bet they refined the hemi tuning over the two year difference. The gains you feel are probably what ours feels like stock with less gains to be had in subsequent model years. (Then they changed again in 08)
