Programmers for 12' and up


Help! I've been searching and reading posts on this forum and others about programmers for 12' - 13' for days. It doesn't seem as though there is one product that clearly outperforms others. The Bully Dog sounds promising. It claims to facilitate the use of lockers and swaybar disco in 4hi but, no one has confirmed this yet. There's also quite a bit of criticism regarding the software and throttle programming. None appear to address automatics trany shifting issues that arise with larger tires. What I need at minimum is the ability to change the tire size to 35s and gear ratio to 4.56. Most should do that. I'd like to hear more feedback from people who are using these things on 12' and up with the Pentastar motor and automatics transmission, the good, the bad, and the ugly.

I'm a bit biased as I come from the LX platform and CMR tunes... but, I'm waiting for Diablosport to come out with their tuner for my 2013 Pentastar. Based on their past offerings, you should be able to do as you mentioned with lockers, as well as transmission and engine mods. Diablosport CMR tuning generally will let you go as far as you like with tuning, and then some. The CMR tuning software is seperate from/in addition to the tuner device you buy online somewhere. Doesn't AEV make a "tuner lite" device that lets you make simple changes?
