Have you tried using the throttle screw or what ever its called on the side of the tb? My tuner hates it when peeps drill the hole out lol. BTW, I have the MTI tb with no hole in it. I works fine just using that screw to let enuff air in.

well with a big cam you would probably benefit from drilling it out a little and also people like to adjust the set screw. What does your tuner say you should do??
