Midgard Industries is an automotive modification and tuning service provider based in Longview, Texas, operated by Charlie Moyer. Its core focus is GM LS-platform engine swaps, EFI electronic fuel injection system configuration, and ECU calibration for street and performance cars. It is not a software SaaS product or e-commerce platform, but a typical niche automotive service shop. Its service area covers East Texas cities such as Tyler, Longview, and Gilmer, while it also offers some remote support.
The main services listed on the website include Holley EFI, ACES EFI, HP Tuners calibration, and LS Swap Base Startup Tune. Specific work includes VATS anti-theft removal, injector data setup, MAP/MAF configuration, fan control, transmission parameters, idle and startup optimization, fuel and ignition table adjustments, log analysis, and revisions. It covers Gen 3 LS ECUs such as P01 and P59, as well as multiple systems including Holley Sniper, Terminator X, HP, Dominator, and ACES.
Pricing is disclosed as starting rates: LS Swap base startup tuning starts at $100; ACES EFI, Holley EFI, and HP Tuners tuning all start at $300. HP Tuners may also require additional credits. The website states that most tunes require 1–3 datalog-based revisions, with a typical turnaround time of 24–72 hours, but the final price depends on the engine combination, platform, and complexity.
The strengths are its focused positioning, clearly separated service offerings, and emphasis on a data-driven workflow of reviewing logs before making adjustments. It also covers many common LS-swap pain points, including VATS, fans, transmissions, wideband O2 logging, and Speed Density. The downside is that it is more of an individual expert-style service, with limited scalable customer support, warranty terms, and in-depth case studies. Some emissions-related settings may involve road-legality issues, and the website also reminds users that they are responsible for complying with local regulations.
It is best suited to vehicle owners and performance shops in the U.S., especially East Texas, working on LS swaps, standalone EFI conversions, or Holley/ACES/HP Tuners calibration. For Chinese users, unless they are working on the same GM LS platform and have the ability to collect logs, communicate in English, and flash remotely, the practical barrier to use is relatively high.
The website itself is expected to be directly accessible, and payments are handled via PayPal. However, because the service depends heavily on vehicle hardware, ECU platform compatibility, and remote collaboration, Chinese users are more likely to find it useful as a technical reference or for remote tuning consultation rather than as a substitute for regular local tuning services.
