Is it worth going for the 3.8 FPR or is it better to stay with the 3.0 bar FPR?

Depends on your setup. If you don't need the fuel then no.

If you don't know why you want one, then the answer has to be NO! It'll give the wrong fueling unless you have a complete remap. Even then the fuel will be metered less precisely. It would only be useful if you're (near) maxing out your injectors, and even then there are other solutions.

As previously said, not unless you are running significant mods, and then only if you have a Unichip or other mappable ECU to set things up properly <img src="/forum/images/graemlins/wink.gif" alt="" />.

I struggled with emissions on the MOT with the 3.8 bar fuel pressure reg fitted, I had to hold the revs at 2000rpm for it to pass.
I really wouldn't bother with one, a good quality chip and maybe a fuel pump will be fine.

I've gone back to the standard regulator.

Have you got a custom chip Jimbo?

I'm using the gtec2 Phil, was going to get the uni-chip but after seeing the results from people with the gtec2 chips I decided it wasnt worth the 300 odd pounds for it when my chip fuels fine on the rollers.

Ok thanks guys, just got a fueling prob at the mo and thought it might help.

ive just fitted a 3.8bar fpr to try and help the maxxed out injector problem some were having when having the unichip mapped at high bhp

iam back at PTS this Thursday so will see how it goes <img src="/forum/images/graemlins/ooo.gif" alt="" />

If you have a fueling problem - up loading the fuel rail will do nothing but negitive or worse over fuel and cause damage.

You need to what you fueling problem is and cure other wise you could at worse face a £3000 plus bill for a new engine - golden tip - dont run with any fueling faults.
