I hope the management is ok posting this file. Interesting on the engine dyno, cyl 2 was showing false knock and reduced the timing to around 8 degrees BTDC and also killed hp to around 460. Another interesting issue was correcting the AFR/Lambda between cylinders with 8 widebands killed 10hp every time we corrected it Time constraint job so it's off the dyno and gone.
I was simply a bystander on this job so I can't share too many details and I assume some would like a gander at the stock file. Ended up around 565hp once finished.
