Or should it be up to the customer to confirm the 'experts' have done their job?
FWIW, I've had no such issues with ESS. They've tuned things properly in house, have flawless AFR readings, and obviously mastered our DME (which is entirely different to the E46 M3).

Agreed regarding the need for vendor testing. Haven't seen people with the other tunes reporting nearly as many issues...

Just one more reason I'm leaning toward ESS. Still haven't received a call from Evolve, by the way... The lack of customer service is actually more frustrating.
