Adjustable Pressure Regulator?

I wanted to get a few opinions...is getting an adjustable fuel pressure regulator and putting 22lb. injectors into a 305, TPI, worth the cost?

No. The injectors are way too big for that car, the ECM is programmed for 19 lb injectors, 22's would dump far too much fuel and to try to back the pressure off far enough to prevent this would adversely affect your spray pattern.

would bumping the pressure a few psi be a mistake then too?

With 22 lb injectors? Yes, that would give even more fuel. On the stock 19 lb injectors you can go 5 lbs higher than stock...about the only thing you might see is a little better idle and a tad better throttle response, but not a HP gain.
