I've never come close to using full retard on the exhaust so I've always wondered if more static advance would be good.

I'm looking forward to your results!

I was making 220whp on a tiny little M50 TB on my M54b30, before I upgraded to stock size.

I didn't gain any power, but the response felt different. Throttle felt more sensitive off-idle.
