It feels as if no boost is available in 2nd gear unless its to the floor. Where before part throttle there was boost. 3rd gear feels faster overall I would say when you first floor it, there’s hesitation, and then starts to go. However my concern still is the pinging... I’m convinced that the engine is pinging, it coincides directly with the valve blocks for timing retardation...
