I've recently brought an escort runnin a 1.8 zvh efi. its runnin standard boost but wen im towards the top end of rev range it seems like its misfirin. iv been told it mite be fuel starvation any help wud b great cheers

 

wot turbo are you running as it may be over boosting you could try an uprated pump and a desent swerl pot

 

it's runnin a t3 but its only runnin 8psi on the gauge
