got our prw4 tune from 5STAR

[LVRVLUVR]

...
installed yesterday...
I'm gonna say if you did nothing else this is a must do... what a difference it makes....

the coach is a total different drive...it stays in the right gear and runs on the lower rpm...... seems to have more power around the 2500 to 3500 range....I cruise 65 at 1800 rpms...and its seems to pull most hills in 4th

I'm gonna hook up the trailer and head up my test 6% hill...

but so far , in or out of CC it runs right along....

another think I realy like was the stop light to stop light driving.... you can just cruise along and it up shifts more like a car... I can drive it around and never go over 2500 rpms..

We just ordered ours. I have read only positive comments and am looking forward to installing it and seeing the results.

Our 5 Star Tune was by far the BEST upgrade we have done. The crazy transmission shift are gone!

Just ordered my 5 Star today. Really excited to see how good it is.

Just drove for the first time with the 5 Star tune and can feel a difference in the shifting. Power seems a better but will need more time behind the wheel to be sure. Scan gauge says mpg is the same so that's a good thing. Right now I would say it's worth the money and will know more when we tow the Jeep.
