Hypertech Max Energy is awesome, if that isnt good enough of a review read my review on hypertechs website.

My review is the fifth from the bottom. Or a direct link is in my signature.

i have the hypertech programmer and a cai and i am happy with them both now i just need to get and exhaust but i have not been able to change my shift points and stuff like that if any one has been able to do this let me know thanks

 

Ok, question...

Those of you giving MPG before and after with tire size changes, did you adjust for the odometer being off with the tire size change before programming? Going from a stock 32" tire to a 35" tire is going to make your odometer read low. Which in turn will make it look like you are getting horrible fuel economy.

If you did do the math, then those kinds of gains are pretty nice.

 

I saw absolutely NO gain when installing my Hypertech, in fact my mileage stayed pretty much the same!

Of course I installed it after a 4.5" lift, 37" tires, new front and rear bumpers and new gears. lol So to me, it was well worth it just to have an accurate speedometer, but the added benefit was my mileage not really going down. In fairness, it did go down, but only by a 10th or two on the highway. The only time I've ever been able to get over 300 miles to the tank is after all of the above were installed. So, is it worth it? I'd say only if you have extensive mods done, added weight, etc.

I can't speak on the added HP, as I've also got a CAI and Flowmaster. None of them added lots of HP, but it sure does sound cool. lol

 

When I matched my tire size to my tire setting with the hypertech, I was seeing 16 mpg around town and on the highway. The long hand nearly matched the computer on the dash. Both mpg figures are reading around 15-16 mpg consistently.

I run...
Hypertech Programmer
K&N Filter in the stock box unmodified
4.10 gears
6 speed manual
35" tires
tires and wheels weigh 97 lbs total

 

I have to give it a thumbs up...

 

I can tell you from experience that a combination of new gears, Hypertech Max Energy, AND cold air intake make for very noticeable results. It's still no rocketship, but that's probably a good thing considering the COG.

 

I took this JK built in 11/06 back for tc shudder and they reflashed it. It would lock up in 4th or 3rd at about 1300r's and I like that but the sudder had to go. It had about 6000 miles on it and when I got it back I felt no more shudder but strangely it will lock up in 4th which is good but not 3rd and that's bad. It may lock at high rpm in 3rd but I want it back to original. Additionally when it locks up it only slides into lockup bringing the rpms down slowly which induces heat and ware.
Will the Hypertech Tuner address the lockup issue like its reported to give firm transmission shifts?
