How much HP?
 

I have installed shorty headers, h-pipe, fenderwell cold air kit, underdrive pulleys, smog pump removed, timing set on 14 degrees, 160 thermastat, TPS set at .974, vacuum line on EGR plugged with BB and one going to fuel pressure regulator plugged also, weld wheels, and 3.55 gear.

Lol.....Why would you plug the vacuum line going to the regulator.

Your car must run rich as hell, with the set-up you have described you will be lucky to be making stock HP.

Later.:confused:

You would be suprised at how much difference it made when this guy showed me this trick. As far a feel it felt as if made as much difference as the headers, h-pipe combined. It really doesn't seem to be that rich. There are some other vacuum lines that were plugged when I got it. I new at the EFI game had plenty of carbed hot rods. I just try trick and see how they feel.
If I can't tell the difference I undo them.

The Dyno is the only real way to know.
