Hello all! I'm after some help with my cams. I've recently fitted reground piper fast road cams to my VR. Since the fitment I've had over fuelling problems and a loss of about 50bhp. I've checked the timing a number of times and it's spot on. Has anyone had any problems like this before with cams? Or am I doing something wrong and not knowing it? I've had the car dynoed before and after, the loss is clear and the power/torque line jumps all over the place after 4000rpm.
