    Question 09-12 ram r/t six speed ngc4a calibration file

    Hello all. My first time posting, sorry if this is the wrong place for questions. I'm in need of a 09-12 ram r/t file hp. This is the only stock performance file for the 65rfe id love to compare differences. Or if anyone knows what direction the engineers went on when calibrating this ram r/t. thanks a lot happy tuning.

    Try this one, by own risk.

    Im using it on my Truck and it works. You will get less Mpg with it, because it skips no shift and shifts down earlier.
    Im not happy with the stock file in Germany, especially down hill is a pain for the breaks.

    MDS is off and some other little tweaks.

    I will try the 392 cam non mds this year, in my Challenger it works great and iits cheap.

    Thanks a lot that works much better then the stock cal. Id like to have know what the engineers were smoking with this one. lol. there must be a hidden redeeming attribute somewhere. but perhaps it was just bad idea. idk thanks again
