Your issues should be fixed then, but really no bs that maf placement sucks! way to close.
Im running a hydra and my maf is just attached to the inner fender.
#1. Try to zip tie it and test that.. before you buy that Maf housing
#2 I agree with ditching the fuel pump and going with a drop in walbro 400 e85 pump or aero.. walbro is cheaper =)
I had a same issue on the dyno, I was losing pressure, so we ran an extra power wire with a relay on it to stabilize the pressure drop. then later on i bought a bigger pump. The wires going to the stock fuel pump are very small. Speaker wire would of been better from the factory!!
