i was driving today and i was in 3rd gear at about 3k rpms and i wanted to make a nice pull so i give the car soem gas to spool up the turbo. but i notice as the turbo syarted to spool up past 5psi the car kinda stuttered a little(im not sure how to describe it). it was almost as if it was running out of gas but then stopped when i shifted. bad spark plugs?
