when i go WOT the car has a slight pulsation, i don't really know how to discribe it, but it's like....rrrrrRRRrrRRrRRRrrrRRRrrrRRR all the way to red line. what kind of problems might cause this? is it a fuel or a boost problem?? i didn't really have time to look at my boost gauge because i was racing some bikes on the back roads. Any help or suggestions would be great. thanks

Brent
