Has anyone bothered with upgrading the fuel pressure regulator on a 3.4 c2?
Just wondering as I've never noticed anyone doing it in a 911. It might be worth thinking about on cars like mine with upgraded exhausts, cats and manifolds as well as intakes.

It's a cheap mod on a lot of cars so it might be worth a look. I know it's more for the turbo cars but just interested to know
 
I wouldn't bother, I can't see it doing anything other than messing up your fuelling. It is a bodge on turbo cars instead of fitting larger injectors.

I have fitted larger injectors before and made parallel fuel rails to suit my needs as well as a fuel lab adjustable regulator. The regulator was needed as the bigger injectors couldn't feed enough juice to match the bigger turbo.

I've never used one on a N/A though
