Default Added 33's with new wheels and leveling kit... Help with power loss
Hey Guys, I just added 295/70 r17s and new wheels.... Since I have a major power loss and loss in MPG... I was expecting some but it went from about 18 to 14-15mpg ... and very sluggish, almost have to floor it to get it up a hill...

Should I just regear? Or would I have any luck with a superchips flash? Its a 2010 sahara, auto tranny

I run 5.13s and my 35s with an auto and its great. A regear would be a great idea, but with just 33's maybe I would try a superchips before I went all out with a regear. Though a regear is the best solution..

Of course re-gearing is THE way to go, but it is spendy. You "may" be happy enough with the Flashpaq. You could try it first and if it's still not enough, when you re-gear you'll still have the Flaspaq for added performance.

I think 295/70/17s measure close to 34s
