Holley EFI Custom Terminator or Dominator Dyno Tuning

TMS offers Holley Certified In-house tuning on all Holley EFI Systems.

Given the nature of most Holley Sniper installs, and the difficulties with warranties, TMS does not service or tune any Holley Sniper equipped vehicles IF WE DID NOT SELL OR INSTALL THE KIT. If you are interested in converting your hot rod to a Holley Sniper EFI System, please give us a call for pricing.

All Holley tuning prices include basic pinout setup of the ECU for things like fans, AC system, fuel pumps, coolant pumps. Pricing can vary depending on the severity of the setup.
