Since mounting the 35s I have noticed that the trans shift patterns are out , hence, the motor is out of its power range a lot of the time. I hear some say the Hypertech unit doesn't work that well, Would I be better off with just an electronic speedo recalibrator. Eventually I will either go back to 33s or change gears, but for now I would like to at least minimize the effects of the larger tires.

Thanks

 

IMO the programmer worked. i just used it about a month ago. shift points are alot better. i recalibrated for the tire size and for gears. i dont know if a speedo calibrator will do much except the speedometer. if u get new size gears, u should recal that also. the hypertech does all of that and more. to me it was worth the money. also since i did it, i dont bog down as much, the engine is holding alot better on interstate at higher speeds. i would recomend it

 

The programmer does add a little power, but most of it is in the 2500 RPM range. If you are running all of the time with the OD disabled, you will probably see some benefits but I'd guess that it will still be doggish until you regear.

 

I will gladly take your 35's off your hand

 

From my limited experience driving an 4dr Rubicon with auto, 35" tires, and the Hypertech on premium settings, I can say that re-gearing is a must as compared to my 2dr Rubicon 6-speed. The Hypertech made the auto liveable, corrected the shift points and improved it some on the highway, but the OD is just too steep for the 35" tires and the torque available from the little V6.
The same Jeep driven weeks later with 5.13 gears installed was a different animal entirely, very quick and smooth in town, and cruising effortlessly on the highway, downshifting smartly and quickly for grades, although still lacking power for uphill acceleration.

With the 6-speed, Hypertech Max Energy, and 35s the 2 door with 4.10 rear isn't bad at all. Sure, 6th becomes more of an OD but you still use it a heck of a lot, and once you get used to it, downshifting to 5th and then hitting the cruise resume is second nature. 5th becomes your "4.88 rear" gear as it offers nearly the exact ratio.
The torque/driveability improvements from the Max Energy are very significant under 2K RPM, greatly expanding use of the lower gears as well.
Just like the auto/5.13, it still lacks power for steep grades at higher speeds, sometimes requiring a shift to 4th at 60-65mph speeds for really steep long hills.
Given the low flat torque curve of the 3.8 V-6, there is only so much re-gearing or downshifting can do.

I have put my "gears" fund on hold and have dedicated the money to a "supercharger/snorkel" fund.

 

Its the best thing about the programer getting you shift points back.
