Loss to a WS6

I agree that exhaust is almost neccessary with a blower setup, it can make the combustion chamber very hot by not allowing the ehxaust to get out. As for the FMU, I have rarely seen a car with a FMU run good, usually the FMU puts in to much fuel pressure early on and makes it run pig rich then when you get into boost it finally levels out. But what you end up with is a good peak power but poor power under the curve and thats what is the most important on a street car.
