Dinan vs Warranty
Got it done at a Auto Performance shop just for BMW/ and they are also a Dinan installer. They were the closest to me that "DINAN" recommend, but they are not a dealer, only a tuner/Maintenance/repair shop for BMW. They can not replace warranty stuff. They told me to find another BMW Dealer that still installs Dinan tunes and try them. If not I'm going old school, Vac. Wastegate. w/ DP
