This beautiful **one-owner 1993 GMC** is no stranger to the shop, and we’re always glad to see it roll back through the door.
It’s already got a great combination under the hood with a **383 stroker, 4-speed overdrive, Dakota Digital gauges, and Holley Sniper 2 EFI** — but the upgrades just keep coming.
This time, we installed a **Holley HyperSpark ignition system**, giving the Sniper 2 full control over ignition timing. After installation, we handled the complete setup and tuning to get everything working together exactly like it should.
The difference was immediate.
🔥 Great-sounding, stable idle
🔥 Dead-smooth drivability going down the road
🔥 Sharper throttle response
🔥 And a whole lot more power everywhere you put your foot into it
A good EFI system is only as good as the setup and calibration behind it, and this truck is a perfect example of what proper ignition control and tuning can do for the entire driving experience.
We can’t wait to see what the next upgrade brings. It’s always a pleasure having this GMC in the shop!
