The founder of Spartan Diesel Technologies, a Ford Power Stroke tuning company, has been jailed for selling thousands of emission-reducing devices, the Environmental Protection Agency found in violation of the Clean Air Act.
The Department of Justice said Thursday that it had sentenced 35-year-old Matthew Sidney Geouge of Hendersonville, North Carolina, to a year and a day in prison for conspiracy to violate the CAA and tax evasion. Geouge was the owner of Spartan Diesel Technologies, which is an EPA document states sold tunes for diesel Ford trucks. Spartan once claimed his tunes delivered the fastest quarter-mile times for Power strokes of 6.4 liters according to a retailer of Spartan’s “Phalanx” tuners. As seen in the video below, the tunes can generate large amounts of soot from unburnt fuel when combined with larger injectors, resulting in an often deliberate side effect known as rolling coal†
Geouge used the profits from the sale of more than 14,000 Phalanx tuners to buy land, build a house and buy weapons and ammunition, according to court documents seen by Market overview† Geouge’s activities caught the attention of both the EPA and the Internal Revenue Service, the first of which issued a notice of violation to Geouge in 2015, to which he reportedly failed to respond. This was followed in 2017 with a $4.15 million fine, which led to Geouge allegedly selling Spartan to Patriot Diagnostics, even though the EPA accused Geouge of simply rebranding his company.
In 2021, Geouge pleaded guilty to the charges outlined above, and in addition to his jail term, he was sentenced to six months of house arrest, three years of supervised release, $1.3 million in fines for the EPA, and an additional $1.2 million for the IRS. Three of Geouge’s co-conspirators were given equal sentences of house arrest and probation, as well as varying amounts of community service and fines.
Geouge is far from the first diesel truck tuner to have repercussions for the sale of defeat devices. in 2021, EZ Lynk was sued by the US government after it reportedly failed to cooperate with a federal investigation into its tuners. Other high-performance outlets have since moved to emissions-compliant solutions that don’t require the removal of a truck’s particulate filter. That’s one of many components designed to prevent excessive pollutants from escaping through a pickup’s exhaust pipe, and often the first component is removed by anyone looking to make more power.
