Had this problem since my rebuild with medium porting and retune.

Any time , any gear, at about 40-60% throttle at 4500 -5500 rpm massive hesitation. AFR's are in check at about 11.4 at this point and boost will be about 10psi. What could be the cause? At WOT no hesitation at all. Is i lean it a little it gets better, but I afraid to lean ir too much.

Anyone had this problem?
