  1. "Why are your tuning prices so expensive?" - ANSWERED

    OST Dyno
    We get a lot of people asking us why we charge $650, $700, or $800 for a remote tuning session on their Hellcat or other supercharged Hemi when they could just as easily purchase a tune online for a much lower cost. A tune is a tune right? Wrong. Many of the folks that are turned away by our...

    SRT Hellcat Performance
    So I recently got a baseline dyno on my car to document exactly how much the 2.85 pulley swap/tune adds... (180 thermo, 95mm throttle body, CAI, axleback, 93 octane tune).

  5. Anyone Know Dyno Shop In Central Jersey? I Can do the LMI VS Stock VS AFE Comparison Everyone Wants!

    SRT Hellcat Performance
    So is there a shop in Central NJ or NYC or surrounding area that might do a few courtesy runs? I figured since so many people on here were wanting to see a bone stock VS LMI comparison. I will have the LMI and AFE magnum force intake on hand for 3 separate runs. It would help the community a lot...

  9. 2016 Stock (nearly) Charger Hellcat Dyno, Good or Bad?

    SRT Hellcat General Discussions
    Hi Fellow Enthusiasts, Today I finally was able to dyno the car for the Hellcat I bought in May. Best run was the first of three, 673.9 HP, 611.44 Torque. (see graph for all three runs, each run was worse than the previous I'm guessing due to heat) Only mod is a K&N cold air intake & filter I...
  10. Hellcat Tuning Q&A's with Josh (HHP) and AJ (HEMITUNER)

    SRT Hellcat Performance
    I've been getting a lot of repeat questions lately, some weird questions and some completely absurd ones, so I figured we should clear the air on Hellcat tuning. Our in-house or email tuning package that we use is centered around Diablosport's CMR software. AJ and Myself have worked together on...
