diggs, i get that but what actually has to be done by them and how long? i have to spell out every question for them to answer just one. figured folks here know more. basically i'm looking at it this way. i buy the turbo, install it myself, bring (hope it will be driveable if i stay off of boost) to the nearest UM dealer, and they flash, and perhaps take it out for logging runs and everything done in an hour or few hours. or is it more involved like have to leave the car for a whole day or days and they have to go on a dyno, etc etc, looking at 2 things here really, 1. the time that i do not have the car 2. the costs involved besides the actual turbo.
