Fuel pressure Regulator

Anybody have experience or a recommendation for an adjustable fuel pressure regulator for a 1984 GPZ1100 running a 4 into 1 Kerker? I don't want to invest in Megasquirt and the original ECU is just fine. I see adjustable regulators on eBay for Mustangs etc., all the time. Some have gauges and some are suspiciously cheap. I just don't know. They used to have factory adjustable fuel pressure regulators available back in the day. It would be nice to know if someone out there has played around with this. By now, most have dumped the injection for smoothbores or what not, for more performance, but I really like the original system, which, "knock on wood", has run fine since I've owned it from new.
Thanks,
Stephen

A source for a fuel regulator can be found at: www.mpsracing.com/products.nos and a new better fuel pump at: www.summitracing.com look for the MSD 2225 fuel pump.

Are you running the MSD 2225 on your B2?

Mike Chestnut of HPU (Horsepower Unlimited) is/was selling GPZ750 Turbo fuel pressure regulators converted to be adjustable. May fit the 1100 as well.

Check out www.750turbo.com . This is a pretty common mod for the 750 turbos and I think many elements of the Turbo FI are similar to the GPz.
