#341, "I thought so too but...." In response to In response to 8
On my latest test I ran about 95psi of fuel pressure @ about 5.5psi of boost. I'm thinking thats a lot of fuel, not to mention my O2 sensor is reading somewhere along the lines of .94-.96v (super rich).So My thinking of the FMU seeing less boost than right at the fuel rail went right out the window. The ONLY reason I would feel more comfortable having the FMU in the engine bay is so you don't have a 6ft vacuume line going to the back of the car. But, I have't had any problems with that. Also, if you get an adjustable FMU, your goin gto want it in the engine bay anyway so you can change fuel pressure ratio.
