I got your predator seems to realy run good. I decided to add Kn Air Charger to it. It seems t ohave a little hesitation when i stomp on it. What can i do??

Well, go into the GM section for starters, then check out the sticky on logging and adjusting the tune. The K&N may have caused the PCM to add too much fuel, and you can trim it with the Predator.

Thanks
