I'm thinking of installing a Superdhip tuner on my 2010 JKU auto. I'm running 33" tires and a leveling lift with the stock 3.73 gearing. The Jeep is pretty wimpy on the highway. Even with the stock wheels and tires it doesn't hold overdrive very well. How much of an improvement can I expect from the tuner?

I do some crawling and would like to use that mode on the Superchip. Is switching from a performance mode to the "crawling" mode something that can be done easily in the field?

 

Just do a search on flashpaq here. There is tons of feedback and most all is good. Its not nitrous or anything, but the throttle lag mostly is gone and it holds gear better. Worth my 300+ dollars.

 

Switching between the tunes is a 5 minuteish process that you can do while airing down don't take long at all.

 

I have a 2010 JKU auto with 4.10's & 33's and the tuner is well worth the money. The jeep holds gear on the hwy alot better and the extra throttle response around town is nice. I can do 75mph comfortably with OD on. And switching between tunes is something that is easily done as well.

 

love my tuner! except when it makes my jk ping..... from my experience they tend to ping more with the 6 speed guys though

 

Try running some seafoam or Chrysler combustion chamber cleaner and see if it helps with the pinging. It did for me. I think many of these issues are due to carbon buildup

 

What does the pinging sound like ???? Anybody have a sound clip.
