  1. Does anyone have stock hellcat throttle body tuning data?

    Looking to see if anyone here has stock hellcat TB data to share? Have a predator swapped gen2 using a hellcat 108 and having issues with throttle failure since we don't have hellcat values to plug in. Using SCT but any data would be appreciated.
  2. High idle predator blower swap 108 TB

    This is a tuning question that I'm hoping someone may have run across before. I have a 2017 GT, Mt-82, ported predator blower, 108 mm Nick Williams hellcat TB(same as Kong and VMP), dw1200's, return fuel system, long tubes etc. Tuners got it dialed in pretty well but cannot get the idle down...
  3. Having some trouble with my 2015 s550 (tuning)

  4. Factory EcoBoost 10-speed tuning - better than GT/PP1 when it comes to downshifting, especially the 3>2 & 2>1?

    So, my '22 GT Premium PP1 (Active Exhaust + Magneride) 10-Speed is in the shop today (A/C compressor took a shit), and so they gave me a rental ecoboost 10-speed. So, I slapped it into Sport +, dropped the shift knob into "S" so that I could lock the paddle shifters into manual shifting mode. I...
