I wanted to do a speed test on my car private road of course and as I accelerated up the gears I reached about 145 mph and I looked at the clock and noticed the rev was just sitting at 5k and moving very slowly and the speed was Bearly picking up, my concern Is that i am on stage 2 with hpfp and my mates car with stage 1 very smoothly and effortlessly went to 160 with no drama at all.
What could the problem be here, I have diverter D so no that and also have the bsh pcv fix?
