Still stock injectors? Your mods aren't radical enough where it won't run on the stock tune just not great. You can start with a mail order tune from Madtuner or PCMforless.
is your car A4 or M6?
i'd be happy to let you use my bin for a starting point, it'll be pretty close. i can't find that cam part# on lunati's site, is it discontinued?
mine is 211/219, 112 lsa.. my heads probably dont flow as well as yours, they're close to stock castings and they're stock sized valves.
pm me, i'll need to do some stuff to it first (re-enable whatever emissions things you still use, and change the injector constant and gears)
