In April of 2017, Dirt Launch Powersports was founded as a division of Beyond Redline Performance, Green Bay, WI, after being approached by pro off-road driver, Johnny Greaves, to modify the calibration on his MPI 155 kit for his 2017 Yamaha YXZ SS. After reviewing the ECU and removing the piggybacks DLP was able to successfully tune the machine utilizing only the factory ECU. This lead the business into purchasing a YXZ and developing an airbox to help extract the most power out of the naturally aspirated version of the YXZ. After countless hours of R&D on the dyno, DLP finally settled on an airbox that proved its quality and performance. In the 2017 TORC series season, DLP stacked up 36 top 5 finishes in 13 races in the Pro Stock class, and 19 top 5 finishes in 13 races in the Pro Mod class. Dirt Launch Powersports was competing against the turbo RZR and turbo Can Am X3 in their naturally aspirated Yamahas in the Pro Mod class. DLP also offers a turbo kit for the Yamaha YXZ 1000R.
