I would imagine that the £650 covers andy's liscense payment to Ecutek and the rest is his time spent mapping, running, checking, mapping, running, checking over and over. In other words a full monty remap. There defo used to be a 'broadbrush' decat remap when I was kicking around and it would be sad if that map has just dissapeared. I'd bet JB still has it on his laptop
Actually, I recall being told to run the car from 20-silly speeds in the backroads of fife whilst John mapped her up to 1.4 bar (!!!!) just to cover mometary overboost, etc. Despite the turbo working above its normal range the car was crazy fast!! Might be worth the full fat remap for that alone
