I have a 416 LS3 based motor in a 4th gen camaro with a Big stuff 3. It still has the coil packs also. This car has been a fu*king nightmare with back firring issues and starting issues. I'm looking for a good tuner/shop that I can drop it off at. I live in GA but will haul this heap out of state as long as I know it'll be fixed right. I know there is Proline and some other shops in my area, but I'm looking for somewhere else.Anybody????? Perferably somebody that is specific to LS motors and my car that can tune BS3, Thanks for the help.
