Up to this point all of the mods that I have done to my car have been done at the BMW dealer of I have done them myself. I am looking to get into a new set of headers and install an under drive pulley, both of which I do not feel comfortable doing on my own and don't want to get killed in labor costs by going to the dealer. I have been searching for a good tuner shop here in New England, but haven't come across any that have rave reviews. I was hoping that someone here could speak from experience of a good shop to go to up this way. Thanks!
