[QUOTE="Blown04GT, post: 5100194, member: 50784"] I think 01cobravortech said this earlier in a matter of words - it isn't the lean mixture that always causes detonation, IT IS THE TIMING. The common misconception of running lean and blowing motors is running too much timing, causing the mixture to run lean, and then detonating. The oh so fatal detonation is not a direct result of the mixture running lean, but because it had too much timing. Basically what happens is the spark comes too late and the mixture has already compressed and heated to the point that it explodes on its own (without spark) and then the spark ignites directly on the top of the piston (the dreadful "ping" you hear from detonation). So yes, get it retuned to see some decent gains, but don't because it is running so lean that it will blow up. [/QUOTE]
