Jestr Tuning started tuning vehicles in 1996.  Eprom burning and piggyback systems were the only ways to properly tune a vehicle in the mid 1990’s.

With over 20 years of experience tuning electronic fuel injection, Jestr Tuning is also well versed in most standalone engine management systems as well as factory ECUs (including but not limited to repair and Eprom tuning).
