Well i finally got my lst2 broken in and my LHS offers a free tune up if you bought the car there. So i took it in yesterday and got it tuned up. They had a line there so i left it there over night. The next day i picked it up and it seemed to run...mostly accelerate...poorly. My Question. Is the mach 427 supposed to happily run rich or could i lean out the low speed to keep it from dieing on idle and bogging from acceleration if i let it sit idling for a while?
