Have you ever heard of BBK Throttle Body's needing a hole drilled into them (like carb's w/big cam's) when you run a large cam?? I gave my engine builder the phone # to FRPP's tech line and he got in touch with a dude at FRPP that runs a 393 stroker with a supercharer. Anyway, this guy gave him some good info (including the tip to drill the hole) and said that the edges on the BBK TB were too sharp and screw w/ the CPU at part throttle...plus make that whistle noise. My throttle body makes a whistle when I decelerate from a hard acceleration, something's wrong...
