Guhl Motors has moved to a larger facility. Please Note our new address: 102 S. State St. Ephrata, PA 17522-2411

We are traveling to a couple racing racing events, therefore, we will not be flashing any ECUs Monday 06/12/2017 - Friday 06/16/2017 and Monday 06/26/2017 - Friday 06/30/2017. Any ECU received during that time will be flashed during the next week. Please plan accordingly.
