So, got my injectors back today from http://www.mrinjector.us/index.html and am pretty happy with the cost and results. He does a complete ultrasonic cleaning and rebuild of your injectors with before and after flow sheets included with your returned injectors. I have peace of mind knowing my JCW injectors are all flowing exactly 376cc. My worst flowing one was 352cc prior to cleaning and rebuild which includes filter,o-rings, pintles etc. Mr.injector charges a flat $16 per injector and $5 to send them back. The other places I checked were $18-21 each if memory serves right. Anyway just wanted to put in a good word for Mr.Injector as I promised him and to let you guys know this is a great service and much better than just running fuel injector cleaner in your gas tank.
