i base it on the fact that he took my car to get a rebiuld and it took him, hold on....... 15 weeks to finish it!!! he lied to me consistantly about how long it would take, how much he had completed and on the price.
only once he was firmly "persuaded" did he move his ass and get it done. i dont hold a grudge anymore cause he's a nice guy and he knows a family member or two of mine, but if anyone asks for an opinion on his work i will tell them my experience
all im saying is he is not the best calibre tunner out there thats for sure
