Ok so basically ive been on a poor mans diet. Basically all I've done to my 89 stang is redo the entire interior, what a chore. Anyway, I'm ready to beef up the 5.0. I already have an edelbrook upper intake manifold so I can add HP to the car down the road. Set up right now is just GT40's and an E303 cam, cold air intake of course. So for starters I'm just looking at the basic 8-15HP gainers. Just bought a BBK 75mm TB, next looking to buy 1 5/8" BBK shorties and either an H-Pipe or Off road X?(Need some opinions there). As some people have read I have been having vacuum problems but I bought all new vacuum lines so those will all be replaced. My question however is... With the new TB being a 75mm will I/should I upgrade the MAF to the 76mm MAF right now or am I able to wait? It's no big deal, I have the money now, just not sure if I'll benefit from it now w/out more beef. Opinions? Questions? Let me hear it. Thanks

x pipes are proven to add a couple more horsepower over h pipes, but it is such a small difference it is really a matter of preference. An x pipe usually produces more of a racey tone, while an h-pipe will give more of a muscle car tone. 75mm throttle body with your mods is pretty big overkill, unless you plan on significant future mods. I wouldn't bother changing the mass air until you are forced to when you have to go to bigger injectors. The mass air would be a pretty insignificant difference for the money.

oh I plan on making much bigger mods. Just saving for the big one. Going to go with a bigger fuel pump, 42lb injectors and 8-10psi supercharger, inter stage cooling system and 4:10 gears. No point in getting a 70mm or something small when I'm going to be building for something bigger.
