Just a short clip of my '03 S with her new brain (ViPEC standalone) and the new (custom made by Bosch Motorsport in their sample shop) 950cc (@3 BAR) fuel injectors. Runs like stock (well as much as stock runs with the CatCam 270/278 profile cam )

 

Not bad for a first start. Now time for the fine tuning. It may be the video, but it sounds like there's either an exhaust leak or a weak chain tensioner. Is that just the vid?

 

It could be the chain tensioner. I just replaced the chain + guides and did not replace the tensioner as it WAS sitting on my desk and I could not find it when I did the job. Noise is coming from the timing cover though. So it is either that or the oil pump itself is ticking (which would be un-common)
edit: found the damn thing finally. Sitting inside of a plastic bag from the dealer on a hook peg at the top of my workbench -_- . Installed and after a short drive the noise has reduced to almost nothing. Residual noise is just light lifter noise from the large cam I think.
