He may not be able to solve the problem with a tune, but he will definitely help steer you in the right direction of the problem if he cannot solve it. The level of detail this guy uses when analyzing engine tunes is meticulous and methodical. He actually has algorithms developed to analyze the data from logging. Most tuners want short logs (2 min at most kinda thing) to analyze because there's too much info - Eugene wants ALL the data so he can run his algorithms to look for various flags in the data and get the full picture.

PM him at ByThaBay and link this thread and see what he has to say
