Customer Testimonials

“The PDI twin turbo setup was installed on my Newell Motorcoach with ISX in it. I have never had so much fun driving a Motorcoach. It goes up the mountains like a car. Words can’t describe how much better it runs. They really have it going on when it comes to performance and fuel mileage.”

“We installed this PDI set up on a CM2350 and couldn’t believe the difference in driveability. Paired together with the new Big Boss Intake and tuning we had massive increases in power and the turbo spooled up almost immediately! This is a highly recommended setup and is a breeze to install!”
