i installed the predator last week, and since then i have got on the go pedal hard 2 times once towing 5er and once not towing. both time i can here a screaching noise. it sounds like a belt, but it has never made any noise when i got on it before. could it be the predator is making power that the belts cant catch up too?

anyone??

I have the same sound only when I'm standing on it, not sure what it is but I am leaning towards a belt or pully bearing

You guys have a boost leak.

Its probably your EGR blowing open from the chip calling for more boost.
Block that EGR... and I think your problem will go away.

While your in there wouldn't hurt to tighten up all your CAC Tube connections and check for any holes in the CAC tubes.
