Lol Leeroy, I heard your car was falsely accused of cam timing issues from a reputable workshop
Don't think it will be the fuel pump
Last year on the ss2 it was running an old walbro fuel pump and still had the issue
Anyways, no one has had a chance to touch the car since the tune as I am busy most weekdays, so will be good to run over a few things over the coming weekends to resolve the issue. It's always good to get some brainstorming ideas
