Default TPIS adjustable Fuel Pressure Regulator

I have found a guy locally that is selling a TPIS adjustable fuel pressure regulator for $50. I have never had one in anything "modern". But is this really needed? I have a 93, and this FPR is built specifically for it. My car will likely be a cam and bolt on 355ci maybe some head work later. FWIW, I plan on getting the tuning software and hardware from Moates along with an autometer wideband setup.

I would say only in boosted or nos applications but for N/A it's not really needed..

I didn't think it was necessary for the simple builds.

They're cool for tuning if you have a fuel pressure gauge to use them with but it's not really something you need to tamper with until you need to beef up the fuel delivery.
