    In my spreadsheet i don't recall putting in any vanos tables other than cobb and some examples to reduce egr effect (shouldn't effect timing at all), it's mostly just explanation of how/why although...

    This isn't the proper forum for N/A high-revving V8's! The S65 can absolutely benefit from cams, until you slap 2 turbos on it! Then while it could still "benefit" from cams it would benefit...

    By timing chain do you mean the chain that deals with cam timing? I'm pretty sure the hpfp is ran off a separate chain that drives the oil pump and vacuum pump, unrelated to cam timing, but I...

    I can't think of a reason to keep them separate, I've never tuned them separate before. Most I've seen trims deviate on meth/tbi cars is 10% and I'm not a fan of "fixing" that mechanical problem...
