After the mapping session I also checked the valve clearances again as everything has bedded in a bit and should have settled. Unfortunately the clearances are a bit higher than I would like which explains the elevated valvetrain noise, and will no doubt cause accelerated wear on the cams. Valvetrain is something that I have limited experience with and have a lot to learn; I assumed that the clearances would close up a bit after the valves have set in their seats but instead the clearances opened up a bit which means other parts have settled.
Also, I had to change the fuel pressure regulator to an AEM unit, as the “Aeromotive” unit started leaking. It was probably some Chinese knock-off unit, despite it not being that cheap. The good thing is that AEM unit is much smaller and nicer.
