Got my injectors back from witchhunter today, they did an awesome job!! Sent them out last wed and got them back monday. Wasnt expecting them for another few days. all new screens, new o rings, new end caps, and they look like brand new!! I sent in my cold start and a spare injector, 6 injectors total and with return shipping was $108. there was an 8.8% variance between the 4 that came out of my motor, although none of them were terribly out of tune I bet it will run much better now. Hope to have it back together for sunflower mine loop this saturday with the new header and exhaust.
