LS Swap & EFI Calibration Built on Real Data
Midgard Industries focuses on reliable LS swap and EFI calibration for street and street/strip builds. The goal is simple: clean drivability, safe power, and repeatable results using real data—not guesswork.
Charlie Moyer
I'm Charlie Moyer, based in Longview, Texas. I specialize in LS platform swaps and EFI calibration using HP Tuners, Holley EFI, ACES EFI, and GM factory ECUs. My work focuses on helping engines start clean, idle smoothly, drive predictably, and make reliable power.
From base startup tunes for LS swaps to full fuel and ignition calibration, the goal is always the same: a tune that starts, idles, cruises, and pulls safely.
What you can expect

- Conservative safety margins for pump gas builds
- Support for common swap needs: VATS, fans, rear O2/cat settings (where applicable), trans calibration
- Carb-to-EFI conversions: startup/idle, acceleration enrichment, and drivability refinement
