From the North American point of view the cam upgrade is wonderful. I added roller rockers at the same time just because I had to remove the rockers anyway so why not remove the studs and grind away the clearance for the pushrods. With standard rockers it might not be necessary and would make the job easier.
I had a locked ECU and it worked just fine for 6 months and then I started getting check engine light so I read the ecu with ProTune and it said “maximum limits reached” or something close to that. Still ran great and started fine.because of that I purchased an UNLOCKED ECU from G56 that is tuned for the cams. That will be a project in a couple of weeks.
I had the AR Stage 1 intake and exhaust already. Is
Oke with S&S Tech dept and they indicated the engine was designed with the larger cams and had to have the smaller one installed to meet European Pollution Spec. The 569 really make the engine purr.
