I have been having problems with the car since I stroked the engine and put it back in. Car was sitting for 3 years before I had the time to get it back on the road but now I have a problem. Car was previously tuned by a reputable shop.

Please look at the knocksum spiking at 36 at WOT. What is causing it to go so high?

reconfigured AFR after having problems and no change. When I lower boost to stock, it goes away but prob still have a high knocksum. Need to do some data collection to see.



What is wrong with my car?
