Next month My m5 engine is coming out and being forged. Car still runs as normal but there has been some detonation on the pistons i found a few months ago. Not sure what caused it i did have a meth issue and i did get some pre ignition with stock plugs earlier in the year either of those maybe responsible. Not going quite as crazy as the others here just rods, pistons with stock compression and some pure stage 2 hybrids.

Car currently has flash, ssp spec r, jb4, bms meth kit, eventuri intakes, and no catalytic converters.
