I need help figuring out my car, I have a fresh rebuilt engine with a ta60 turbo, 55lb injectors,front mount intercooler, 206 cam, and cast iron ported heads with bigger valves, I have about 400 miles on engine and am having a very high knock problem between shifts, my scanmaster shows 38 degrees retard and around 840 02 counts around 58mph and it also happens when I am cruising at 65 mph on the freeway and floor it I can see my scanmaster see the same high numbers but when I start off in first gear there is no knock till it starts to shift and then I see it and let off the car. I am running 44lbs of fuel pressure with hose off and 94 octane fuel, I have checked motor mounts and the down pipe and nothing is hitting, I also tied the engine down on the drivers side so it will not move under torque, the car shifts fine and I keep turning the wastegate down and it does not improve at all, I would also like to know if this problem which I believe is false knock will hurt the head gaskets in any way, I also pulled the cam back out to make sure it was not worn and it checked out ok. Any ideas would be appreciated. Thank You
