HI All,

I have fitted a fuel pressure regulator into my DC-2 lately and I noticed the following three things:

1. I get a higher idle than before. Around 1100 rpm (before it was 900rpm)
2. Vtec has became less obvious, but I can still reach 8700rpms
3. Car seems to be more noisy than before.

Are these symptoms normal after fitting in a VRS fuel pressure regulator?

Thanks.

btw, how do i change the pressure of the regulator?

 

Get it tuned on a dyno with a wideband O2 sensor...

 

the symptoms may be normal after changing the fuel pressure. do you have a gauge? whats your static pressure a 0 vacumm?

and why do you think you need to change your fuel pressure
