I had the car on a rolling road and all was perfect, but just after the car started running rich ( I have a Stacks Labda gauge fitted) it was also lumpy etc on tick over but on boost ran ok.
Competed with it last weekend and half way up on the first run it poped and banged then cleared and run good all weekend starting and runing perfect, pulled my best finish speed ever. ( cant read the gauge when competing)
Took the car out tonight and its running smooth but notice that its fual air ratio is not going below 14 on boost, ( it was mid 11's on the rolling road) took the plugs out to check and they are a chocolate brown colour and the car didnt seem to knock but its not easy to hear that now as its stripped out....
I cant figue out why its gose to one extreme then the other?
Any ideas please? As i am out again next weekend. HELP..
