I pulled into the service garage at my Ford dealer to set up an appointment, the service advisor hopped in, cut the wheel hard to the left and called out a tech from the garage. He went around to the passenger side with a flashlight and a mirror, looked underneath for about 30 seconds, pronounced the car fine and I drove away 5 minutes later.
Maybe it's just me but I see no point at all returning a car to stock when you pull through the service bay with custom exhaust and downpipes, turbo's wailing away, car slammed to the ground so low it looks like it might drag the rugs out as you leave.
I make it a point to let my service advisors know I don't want them in the ECU just to avoid getting my strategy code changed.
