BMS (Burger Tuning) F10 M5 S63TU preliminary Stage I tune testing and Dynojet graphs - 628 wheel horsepower
Was able to get out and do some preliminary dyno testing. Granted, the car has only 200 miles on it. So much more will come. Testing was done on ~94 octane with carbon filters removed. After the stock runs in 4th and 5th gear I did a few Stage 1 tuned runs just for comparison. While the car makes more power in 5th on the dyno it hits the 155mph speed limiter at around 6200rpm. In 5th gear on the dyno the DCT also decided to lower its torque targets in the 4500rpm range.
Since I mainly just wanted to get some baseline figures I didn't spend too much time digging in to what is going on there. But I saw similar behavior in our N55 DCT 135i before we were able to resolve it on the tuning end.
Net/net happy with the figures. Next up I'll do some VBOX runs and work on stronger tune development as my schedule permits.
