What do you mean by "blip" the throttle? quick "slap" on the throttle?
I thought i had a small missfire at full boost today when i floored it in 3rd to check oil pressure. Thought it could be because i didn't have enough fuel on the tank or the fact i didn't check the spark plug gap when i raised the boost a few days ago.
Other than that the engine just feels very healthy and noise (tappets) free.
