Feets, leave it in drive... I had a E55 with a "level 1 tune" and went 11.80 with a "spinning 60ft". I have never heard, though I am sure it happens, where a driver controls the shifts on these cars and runs better than if they left it in drive. Just my .02. And for fun, with a tune, I estimate it to run in the mid 11's if you are on a decent tire.
