How to tell if dealer flashed over tune
Does anyone know a definitive way (besides butt dyno) to determine if the dealer flashed your tuned ECU back to stock while in for a service?

Lol trust me you will notice it during acceleration. Specially above 50 MPH it just doesnt feel the same. I noticed it inmediately when my mechanic reflashed back to stock by mistake, sent it back to kleemann and back to normal

To answer the question, no, I don't think anyone has come up with a 100% reliable way to confirm tune vs. stock. Maybe the people that program should figure something out along those lines!

If a dealer did do that, it would say it on the work order. "ECU reprogram of flash" or something of that sort to a "updated version x.xx".

+1 --> tunes are the simplest, easiest way to put a little more pep in the step, regardless of how you feel about concerns like engine wear, etc.
