had a little mess with the car today and all the sensors etc have been pulled out or messed with

the messers..

even had no air filter

so sorted all that out with a mate, and now got a fuel pressure gauge fitted, it sits around 3 bar on idle (with power boost valve) but when revved it drops to 2.5 bar, is this meant to happend, i thought the pressure would have gone up?

any help would be great

its a electric pump it can only suply that pressure and i wouldnt be surprised at 0.5bar pressure difference when reving a you are releasing pressure...

cant say thats 100% right but i will stand corrected im sure.

get rid of that crappy fse boost valve

could either be

gauge reading wrong
fse boost valve playing up
or fuel pump giving up, not haveing the flow needed when under load
