I think I read on the Turbo build threads that stock MAF's are good up 450-500hp. I could have read wrong but I think thats also why most say the JET MAF was a waste of money.

Also i have a feeling that whole intake crossover issue and welding of the downpipe will require a little more know how than i have.
I hear ya, I work everyday as well. As I recall you did the cam before the intake........that's why it didn't respond to the cam.

thanks, yeah that's just about the same size as the TB, it's probably not restrictive, at least not worth the hassle or cost of replacing.
