My friend is in the middle of putting aan ls3 376/480in his Silverado. Iam the only one in my areawith tuning software but I'm still in learning stages. Would it be unwise to just load a stock ls3 tune in the trucks ecm and see what that gets us? One problem Isee is that an auto ls3 tune is going to be for a6l80trans and his truck is equipped with a 4l60... Any advice?
The engine is going into a 2008 Silverado nbs.
