DCT M5s are trapping 131-132mph with bms set to 3.5 and exhaust on 93. Btw, that is not ATCO. LP700s are trapping 136-137mph with 700hp, 4000lbs and the added drivetrain loss of awd. I would say a true 800hp m5 with the trickery of dct should do 140mph traps.

100hp shot on a turbo engine usually results in more than 100hp due to cooling effects, although if you are running methanol or e85 the effects may be less, however you will still get a cooling effect that is more pronounced vs an NA car.

The reason your dash command is showing 22psi and the bms is showing 26 is probably because the dcommand app reads off the elm327 interface tied into the cars computers. The bms take the signals from the boost sensors and fools the cars computer into thinking it is running stock boost ~22psi or whatever boost needed to run what the computer believes to be stock hp.

You should be getting at least a .5 reduction in 60-130mph with a true 100 shot. Something is not right with your setup.

I would disactivate methanol, nitrous, and set bms to 0 or remove bms altogether, you don't need it. You are just tricking the tune which has already messed with the stock maps and cars computer.

Check your 60-130mph the following way:

1. Tune-only
2. Tune with introduction of nitrous (50-100hp) and racing gas.

Personally, I would not be messing with nitrous and the high torque of smallish stock turbos. If I were to activate nitrous it would be gradually past the midrange at 4.5k or higher for fear of bending the rods on these cars. I don't know at which rpm you are activating just being proactive.

Anyways, this is the way I would have proceeded:

60-130mph or 1/4traps:

1. Tune-only
2. Tune-only with upgraded turbos and higher boost, more fuel, tuned for race gas.

Herein you should find your 140mph traps and high 5s 60-130mph

However I do understand that no one has programmed a tune for upgraded turbos, so that may not yet be a possibility....
