After I flashed to BM3 stage 2, I noticed a hesitation from the car. I thought it was the spark plugs, so I swapped out the factory for 1-step colder spark plugs. NGK SILZKBR8D8S (97506)
Car ran much better with the new plugs but the hesitation was still there. Someone suggested the xhp transmission tune to raise the Torque Limits and shift faster. Now I have no hesitation and the car feels faster and smother.
