Mike's--owner of EFI Connection--first project: a Chevy S10 pickup truck🚨

Over the years, this vehicle has been a prototype for our EFI 24x Conversion Kits. Many hours were spent testing and operating this vehicle to make sure we are providing customers with the highest quality and efficient conversion kit 🔋

Fun fact: This project introduced Mike to prom tuning with the 167, 730, and 727 ECM 💻

Check out our versions of conversion kits here: https://www.eficonnection.com/home/category/engine-hardware/crank-and-cam-signal-kits
