35" BFG KM2 & Shutting OD off

I put 35" BFG KM2 tires on my 2008 Rubi along with a 3" Rough Country lift. I really like the set up and have noticed a slight difference in "power" when running 55-65 mph. I'm considering a performance tuner but when I turn off my overdrive, the RPMs increase and the Jeep stays in 3rd longer thus providing better power at higher speeds. Beside a decrease in fuel economy, are there any long term problems that can be created by driving consistently with OD shut off? Thanks!

Nope. Fwiw I've been running Superchips 93 tune for over a year.

I'd still pick up a tuner/ProCal to correct the speedo and input your gear ratio for shift points. 2010 JKUR, 4:10s, 35" Nitto Trail Grapplers for the past year and it's been okay, luckily I live in a flat city. OD goes off the second I start up the Jeep, it's only usable going downhill, lol.

Thanks for the replies everyone. Planning on a tuner for sure but is sounds like shutting off the OD is a feasible short-term solution to improve the performance.

I used to run with OD off, until I went 5.13. Do yourself a favor, install 5.13's

I would think that the only downfall is that you have a 3 speed automatic. When I was a kid, my dad had an AMC Gremlin...with a 3 speed stick.
