    I tried that a couple weeks ago with my stock plugs. i made sure it ran good in speed density and then tried plugging the maf up and it did the same thing

    still having this issue.. i dont know what is going on the last time i tried hooking up the maf it tried "idling" at 5500rpm.. no leaks anywhere in the system and i have tried and tried and tried to dial in maf scalings and maf correction table.. it just bucks and leans out to 18:1 at 0 hg? anything in boost runs perfect, below 5 hg runs perfect.
