The Diesel Performance Podcast is the official podcast for the Ultimate Callout Challenge - a performance diesel event like no other. By invitation only, a couple dozen trucks and drivers will compete this April in Indianapolis - they'll drag, pull, and dyno against each other for the ultimate bragging rights. Last year's event resulted in several trucks running over 2,000 horsepower.

This is our first profile of a UCC participant - Nick Priegnitz of Calibrated Power Solutions. The DPP plans to interview all the participants, so we thought we'd start with someone close to home.

CPS will drive a 2011 Cummins dually with a displacement of 10.4L - increased from an 8.9 ISL. Twin 14mm fuel pumps and 500% over injectors from Exergy. DT's UCC truck will also sport a 10-foot bed instead of the eight-foot factory configuration.
