PPEI is making great strides in expanding the performance of on-highway vehicles and only offers emissions compliant tuning.
PPEI believes there exists (and has always existed) an exception under the Clean Air Act for modifying emissions and emission controls for motor vehicles that have been permanently converted to off-highway race vehicles. In response to EPA's public position and its NCI enforcement, effective 9/16/2019 at 2pm, PPEI has halted sales of race products. PPEI will continue to sell its products designed for on-highway use and is making great strides in expanding the line of on-highway products that deliver the performance that our customers desire.
The EPA has taken the public position that a vehicle designed and sold for on-highway use, such as a common rail diesel pick-up truck, can never be converted to an off-highway, race vehicle if that conversion impacts emissions controls or emissions. The EPA is currently enforcing this position through the EPA's 2020-2023 National Compliance Initiative (NCI), as well as other methods.
