Re: Superchips 3875 advanced transmission tuning help

Although the ATT App. setup looks a little intimidating, it is really no big mystery. The way I started with mine is to identify the things I didn't like about the up/down shifts and the torque...

Re: Bump stops after SRT install

You need the SRT bump stops which are shorter. I had the same problem when I put the Eibach SRT lowering springs on mine. Bottomed out all the time. Since changing them (they came with the spring...

Re: diablo intune

At least the MRE's are better than the old K-Rations we used to have to choke down. Pop corn would have definitely been better too.
