We recommend this for all A50 & T87 controllers. It has an aggressive Line PSI slope which will model a torque curve 100% above stock. The line PSI is modified in such a way that the truck will still retain good mileage yet hold high line psi (close to 245-300psi under full load) following this torque curve. Line PSI is increased across the board, so as a result, fuel economy may be lower in some cases.
This tuning package can only be installed using an EFILive AutoCal V2, FlashScan V2 or AutoCal V3.
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.
