So I installed a blow off valve on my lmm, hooked every thing up and the truck kept throwing maf codes 0101 and it would go into reduced power mode, did that about 25 times or so stoped for a day, then went into reduced power mode with no codes, had it towed to the dealer and they pulled off the wire that was hooked to the gas pedal and replaced the egr valve even know I have it blocked and the truck runs fine any one else have any kind of issues like this?

you can try to clean your mass air sensor and air filter but I don't think that is your problem.I think When your valve blows open and dumps boost your ecm freaks out thinking there is a problem with air delivery. I'm no expert but I think with a blow off valve you increase your chances of over speeding the turbo.

Pretty sure my problem is the wire that hooks up to the gas pedal unhooked that and every thing is peachy again I just dont know any other way to hook it up.

The LMM MAF's are really touchy, I know of a truck that would constantly set the code because of a small boost leak. Not sure if once your valve opens is creating the same scenario.

This will negate the "cool sound" but could help your issue...Plumb the outlet of the BOV back to the intake pre-turbo, ahead of the MAF sensor. Best suggestion I can make short of Having an EFI tune made with that code dis-abled.
