Oil Color

Maybe a compression test or better yet, a leak down test. Make sure it's not too rich, sounds like you took care of that. Are you doing short trips, or nice long runs that get the oil up to full temp? Oil is cheap, you could do another change before a longer trip.
I haven't yet tuned the car fully, I do think it may be a little rich just not at the point of flowing fuel everywhere like it did when it sat, and the trips are at max 20 mins at a clip so getting to a good solid temp, which I am also combating at the moment. Thanks for the input, Ill look into a compression and leak down. Any recommendations on how to do a leak down?
