" Hey guys,
Had a chance to dyno a 335is today. He's running JB4 G5 (ISO_21 firmware), a new backend flash we made a couple weeks ago for DCT cars, BMS downpipes, BMS DCI, BMS CP, ETS IC, E40, and a BMS meth kit. All runs were done on map 7 which targets 18.5psi peak tapering to 14.5psi at redline. Runs were done in 5th gear and temps were in the high 70s.
Car performed flawlessly on the dyno and set a new N54 stock turbo power record. It's a touch over advanced for E40 @ ~6300rpm but the owner plans to run E50 and shifts around 6000rpm anyway, so we decided to leave it as is for now. We'll collect some additional road logs for further evaluation. The car is an absolute beast and he reports no DCT trans slippage.
