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).

Current List of ECU Platforms we service:

In addition to the Standalone tuning options, we also offer re-flashes for many vehicles utilizing open source applications and our Tuning partners.

Traveling tuning, remote tuning, dyno days, and wholesale pricing for shops is also available, contact Jestr Tuning or visit the tuning section of our website for more information.
