EFI Tuning

We offer custom calibrations for 1985-1992 TPI, 1992-1997 LT1/4, and LS powered vehicles. For 1985-1993 vehicles, we provide a custom-programmed PROM we send to you. 1994-Current vehicles use "Flash-Style" computers and you must send your computer to us for recalibration, but for the early chipped computers we just send out a new chip. We can configure a program that will run a stock engine with emissions and vehicle anti-theft deleted for a street rod application all the way to a fully customized program to control a 500+ horsepower drag race engine. Just call us with your specs.

* Our calibrations can only work as well as the engine combination! We often have customers call with a cam that is mis-matched, heads that are too big, incorrect injectors etc... Call us first! We can help you decide what works best for your intended use.*
