Underfueling Problem- help needed!

[Scamper]

Right lads i got the car dynoed on sunday at the show, and john at wcp told me she is underfueling, he said it aint good for the car , and that constant hard driving could resullt in a blown engine.

Basically i wanna no how you would go bout sorting this properly, the car is running perfect if not driven hard, but wanna get this sorted, so can drive her on

Wat would i need to do?
Fuel regulator?
New fuel filter?


Thanks in advance lads

Up rated fuel pump and a decent map from Westward.

some sort of fueling controller like apexi neo safc2.or you could go with some thing better like an emanage.or more expensive a standalone Ecu

first,you need to tell us exactly whats in your car at the moment

how badly under fueling is it? a print out of the afr's from the dyno would be handy

[Scamper]

I dont have a print out, but wen you put the foot down he said the dyno should read from 10.0 dropping rapidly as you increase throttle, so goin from 10.0 down to around 3.0 at full throttle, where as wen i put the foot down in my yoke it goes from 10.0 up to 17.6 at 5500 revs!

Sorry if that means nothing or isnt explained right but dont know much bout this at all!

I agree with Mick here,had 14a once with same problem,had bigger turbo on it but uprated pump,injectors and seen westward,he mapped the power fc and it was perfect then.
