this dosent happen every time but sometimes when i am going WOT in the upper gears (3rd or 4th), i will get weird issue. it almost seems like fuel cut at around 5500 rpms becuase the car will just lose power for a moment then i can go again. i am showing no knock (flashing cel), but i have not datalogged this because it is infrequent and hard to catch. i am stumped as to what it could be. i am running 20 psi on a rev5 utec and i have fuel cut set to 22psi. i am not showing through my boost gauge that i am hitting 22psi. im just looking for ideas as to what it could be cause im stumped. its happend maybe 4 times now:confused:

It could still be hitting boost cut. The factory sensor is different from the boost gauge, and 2 psi variation is easily possible (even with a quality gauge). Try logging.
