  2. How To Read and Understand Datalogs

    SRT Hellcat General Discussions
    I have been datalogging for a year now. I use Diablosport and Tim Barth tunes my Hellcat. While I do look at my datalogs, I honestly do not understand them. Can anyone provide some good resources to begin learning how to understand datalogs? I am not wanting to adjust the tunes, just understand...
  3. To Mod or not to Mod???

    SRT Hellcat General Discussions
    I suspect this question is very popular among HC owners, but want to get people’s honest opinion here as I just bought a 2018 Charger HC that has 11,000 miles on it. It is completely stock and I would like those in this community to weigh in on the pros and cons of tuning and modifying this...

    SRT Hellcat Maintenance
    Taking my cat in to the dealer to have oil changed. They have always done well for me at this. But this time they want to do some recalls. One being the cruise control re-programmming. I made sure to tell them it has been modified and tuned and i dont want them reflashing it. The guy at the...
  8. Diablo tune changing AFR to 9???

    SRT Hellcat Performance
    So I bought a diablo intune3 with an unlocked pcm. I installed a basic can tune just until I get it professionally tuned and it dropped my AFR to the 9's! Idling or WOT still 9. I deleted the tune and restored the factory tune and the AFR went back to normal. I then tried the 93 LMI can tune...
  9. "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...

  14. Thinking about Tune from Tim Barth & Pulley...Have questions

    SRT Hellcat Performance
    I am thinking about a tune from Tim. I know I can swap back to the stock PCM when I bring the car to the dealer. From the input I have received from most, the 6.2L is pretty bullet proof and a tune from Tim would net me about 700-720 rwhp with a LMI intake. I was thinking about doing a 2.85"...
  15. Aftermarket Calibrations

    SRT Hellcat Performance
    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.
