ajustable fuel pressure regulators?????
i have an 88 f250 5.8w efi and am looking into adjustable fuel presure regulators and was looking for some advice. what brand to use and what pressures to use. The motor is mostly stock. All smog has been removed. egr block off. true duel exhuast and high flow air filter. There will be much more in the future but would like to bump up my pressure for the time being.Any suggestions on brands, where to buy and what pressures seem to work good would be great!!!

What do you hope to accomplish with this? Doing this won't add any power, every time you increase pressure the computer will reduce injector dutycycle so the engine will not get any more fuel. The stock EFI system will support around 300hp and all you go to do to get there is let the motor breath.

the computer doesn't know what pressure the fuel is at as it doesn't monitor fuel pressure. Upping the pressure will increase hp but it would be min. future upgrades will include heads, cam possibly mass air conversion etc...

No it won't increase HP just fuel consumption in open loop.
