[russnova]

[Pistol Pete]

When you say dip, a loss of power? Standard engine? What mods have you got?

I preume the car has a blip of lost power, Mine does the same so im no help lol

[russnova]

yeah loss of power only when i first accelerate then clears.it's got green cotton air filter an power cap.

Break up of a lead, fuel related...could be a whole number of things TBH.

[AlexW]

Yep.

I presume the EML isnt on at any point?

[russnova]

no eml doesnt come on.could it be not enuff fuel pressure?

[jono395]

Fuel pressure regulator..

My XE did the same. If running a higher fuel pressure.. i cant stamp on the pedal, else it bogs down..

Otherwise pressure too low?

this sorted my problems though.

With a powercap, it should just move the power up the revs abit.. so from 3k, to 4k.. if its kept in the higher revs it wouldnt do it.

[russnova]

would it be worth trying a power boost valve?

[jono395]

get the fuel pressure checked 1st. Does your fuel pump prime?

[russnova]

yeah mate is does
