need help having serious problem with predator

[tonylukejr]

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

Tony, I can almost guarantee the problems you are having are due to predator canned tune + supercharger. If I were you I would not use the predator unless you get a custom tune done for your vehicle. I am no expert but I'm guessing your a/f mixtures are all out of wack. Some other forum members will know a lot more than I but my guess is your running WAY too lean which could damage your engine.

Do a search on predator engine death. I'm sure you'll find beancounter's advice right on. I'd call GSM as they probably have some pretty good tunes for your car already since they've got a lot of experience with the diablo and their own sc.

Yes....you must get a cmr tune with any mods other that exhaust and cai with the predator!Do that and wow.....youll be smoking!Look for cmr tuners on Diablo's website....go and dyno that bad boy and let us know what you think
