Ive got sone spare parts around for a turbo build for my 1997 f150 i just traded my 1976 f250 for
I know all of the turboing crap and a/f ratios
And that i need injectors and tune ect

Problem is that i cant find a 1.5 or 2 bar map or any other thing like it to tune the 4.6 ... What do the mustang boys tune with ?

 

You're thinking gm stuff.
Mustang guys tune with the maf, with incoming air, not with map.
If you're running a manual you can swap to mustang electronics and have much nicer tuning ability. Or if you're auto, certain ecus have better tuning capability than others.
