1994-2003 7.3 Powerstroke

7.3 Powerstroke

Using Sniper Delta Force and Power Hungry Minotaur software, Gearhead Automotive Performance has developed killer programs for the 7.3 Powerstroke.Completely stock truck or aftermarket turbo and injectors? No Problem!

We can handle these and anything in-between as well as radical combinations with the largest injectors.

Do you want programming that gets excellent mileage and acts like a stock truck until you pin the pedal? Do you want programming that doesn’t belch smoke every time you try and merge into traffic? We can do that!

High Idle

Aids warm-up and running accessories with heavy electrical demand or better air conditioner performance in the summer time on long periods of idling

Street Muscle

Street Fury

Good for extra passing power (must watch EGT) and sprints from stoplight to stoplight without belching tons of smoke

All Out

This file definitely scoots with a stab of the throttle, with power gains over tune 5. This does depend on the condition of your High Pressure Oil Pump (HPOP) and its availability to produce enough volume to the injectors.

Default files available for 94-03 7.3’s with single shot injectors (custom files by request):

Heavy Tow

High Idle
