    I couple guys were asking me about aftermarket calibration to improve Horsepower and Torque. Its an additional step for you HellCat owners because of the encryption added to your computer. Most guys are buying a spare ECM and having a baseline OEM calibration loaded into the spare, and sending it off for modification.
    Here's a link to have someone with HP Tuners access your computer:

    Enjoy,

    So there is no confusion,HP tuners PCM modification will not work with the Diablo system, Diablo has their own.

    No, it's service that needs to be paid for, HP Tuners, Diablo, or Hemi tuner/Diablo

    Thanks Top Cat for clarifying this
    I have wrenched before on a kenne bell setup and loaded tunes with the trinity before. I also have a spare trinity at the moment that I would like to use.
    I would like to do a 2.75 upper pulley and a driveshaft
    I see HHP has an ECU package, I can't seem to find info on the hemituner/diablo setup
    Any recommendations ?

    Thanks

    Zip, HHP uses Hemituner for their ECU's, when you use HHP you get a lot of resources to go with the package, including all that we have learned in testing Linda's car.

    Right On, Thanks TC

    will be calling them on Monday

    PS - Do you think the stock crank pulley would need to be pinned with a smaller upper pulley ?

    I believe the stock crank pulley will not turn any faster, of your only changing the snout pulley,,, again this is my belief and could be wrong..

    HP Tuners BETA platform recently gave us access to the transmission. So now you can expect firmer, quicker, shorter shift and allow for differant gears and tire sizes once calibrated.
