EFI Live AutoCal loaded with proven Fleece Performance tuning
The 650hp Cummins power package is a proven combination that will not disappoint. It was engineered to provide great drivability combined with safe top end power. As a result you will see lower EGT?s, increased fuel economy, and stock like (or better) spooling. We build, drive, and dyno this package almost every day at Fleece Performance and we?re confident you?ll like it just as much as we do.
