Default Fuel Presure Regulator Mod?

Does the fuel presure regulator modification as described in C4 tech tips section really work? Has anyone else tried it?

Don't do it
Buy and adjustable one if you want to mess with the fuel pressure. With that so called tech tip your fuel pressure will be max all the time. Not a good thing

Thanks, I think I'll take your "tech tip" advice.

With the vacuum removed, it will call for full fuel all the time. Get an adjustable FPR if you want to make changes in your tune.

does anyone check these "tech tips" for accuracy when they're submitted? Just read this one and I quote: "if you can stand the noise you can also spring for performance mufflers and obtain a 30-50 HP increase plus a torque increase you can feel." dang I need some of those mufflers! I'll be happy if I get anywhere near that increase from my long tube headers!
