I have installed the 91 octane tune and everytime I go to floor it, it disengages the accelerator. The car continues to run but it's almost as though it puts me into neutral, except the engine won't even rev. A red lightning bolt in parenthesis flashes up on my dash and I'm forced to pull the car over. The only way to get it running normal again is to shut it off and restart. If I drive normal without "pushing it" I have no problems. but once I speed up it starts all over again. the mods I have made to the car besides the predator are a gsm supercharger and cat back exhausts. prior to installing the predator I had no problems at all. I put the car back to the factory stock setting and its working fine. any thoughts would be appreciated

Thanks
Tony

Its going into Limp mode. You gotta raise the rev limiter.

Also, you really need a CMR tune if you don't have one. The canned tune will not work properly with the supercharger.

Duude, please remove the Predator tune, YOU WILL damage your engine with the blower on there, these tunes are NOT setup for forced induction and given the nature of the weak pistons in the Hemi's it will not take long before you damage something.
You will need a custom tune for a supercharger with the proper parameters changed.
