    Hello guys so I’m planning to modify my Hellcat.. I want to start slow by adding a pulley I already have CAI and catback installed.. I’m confused should I go with upper clutched pulley 2.85” or lower ATI 10%? I heard with the upper pulley I’ll need at least to install demon injectors and it’s...

  4. Dodge Charger SRT Hellcat
    Hey everybody! First post! I wish I had a better post to start with, but unfortunately I don't. What I have is a dead HC, no warranty coverage and I have now been labeled a criminal mod-er by Dodge. Yes, I made the mistake of listening to my salesman and I am now paying the price. I can go...

  8. Dodge Charger SRT Hellcat
    I have been looking to tune my car to do a cat delete and do some dyno tuning. Car has about 2350 miles on it. Do you guys think I should just "send it" and cat delete and get some good tuning on the car or ride the warranty out.

    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"...

    So I bought the Diablo pcm and installed it and now I'm stuck with my factory one sitting around. If i send it to Diablo and have it unlocked, can I sell it to a friend and him be able to use it on his hellcat? That was he can get a pcm for 250 Instead of 800
