What is the best programmer on the market for the money. I have a 2010 with 35 in tires and it has killed the performance. No get up and go

 

Superchips Flashpac let's you do quite a lot.

 

AEV ProCal.

If you would rather have a tuner instead, there are several good options out there, just compare the functions and see which fits your needs. The Flashpaq probably has the best reviews and largest fanbase here.

 

I'd go with a tuner and skip the ProCal. I didn't notice any performance improvement with my ProCal.

Hypertech has an impending (Nov/Dec) software update that will put its abilities on par with SuperChips. Check out this thread:

I have just recieved a programmer from them with the "new" software and been running the "REGULAR" tune for over a year. They now have a tune specifically for the VIPER throttle body mod.

According to the November 2011 Off-Road Adventures magazine, the JK Max Energy now has:

Optimized power tuning (same old feature)
Adjustable throttle-body tuning (specifically mentions the Viper)
Adjustable throttle response (looks like it will compete with the SprintBooster)
TMPS adjustment (about time!)
Multiple idle settings (very cool - especially the "automatically raise the idle rpm to provide full alternator charging capacity" when winching feature)
Top-speed limiter (always advertised, never available)
Rev limiter (always advertised, never available)
Cooling fan on/off temps (same old feature)
Tire/Gear calibrations (same old feature)
Engine fan on (new and very cool! pun intended)
Disable traction control (Rubicon only - great to get rid of that POS!)
Enhanced sway bar disconnect (Rubicon only - 2wd, 4wd-hi)
Enhanced diff locker (Rubicon only - 2wd, 4wd-hi)
