Scirocco Register

is it possible to adjust the fueling of k jet . i've just completed a 2 litre 8 valve conversion on my gtx and the car runs really well while the engine is warming up .once up to working temperature she feels abit flat at high revs ,i'm thinking that perhaps a bit more fuel may be needed .is there any way i can achieve this .i'd be grateful for any suggestions .

You need a pressure gauge set to test K-Jet. They are available from USA for a decent price, or borrow one. That's what you need to correctly adjust your whole system. If you suspect it's going lean at high RPM you can fit a 16v control pressure regulator, they have a vacuum hose to add extra fuel under high loads. Make sure it's adjusted correctly though. For details search on Club GTI forum- they have some good FAQs regarding this.

thanks for that, when i bought my audi throttle body it came with a warm up reg with an extra pipe connection on the side so i guess this is the 16v part you mention .i'll look on club gti before i fit it .
