Six figures a year is hardly a lot. Especially when you consider the overhead of operating a business, when the minimum amount of insurance you need per customer is basically $3k.
Besides, there's literally no reason to not to just send it over. It's commoditized at this point.
Oh, believe me, I know.. There's a lot of problems that exist on the track that show their head around the 1000hp mark that don't show on a dyno.. That bitch should be on the track after every change or so.
The likely problem was that the car was 'awake' when you disconnected the wastegate and the TMAP in the chargepipe.
The car registered this as a problem, and doesn't clear those on their own. You should be good to go now.
