UCC Qualifier Kelsie Epps has one goal at the upcoming Ultimate Callout Challenge - beat Charlie Keeter! Epp is a qualifier at this year's event, which means she could return as a competitor if she finishes in the Top 5. You'd think that was more important than beating Keeter - but no - the rivalry is more important. Kelsie's truck is now a triple turbo monster that's undergone plenty of changes to prep for the event. Like most qualifiers - and competitors - she's hoping to get through each event - drag racing, dyno, and sled pull - without breaking.  Paul and Chris also welcome Duramaxtuner lead diesel tech D.J. Wlasiuk to talk about his latest adventures in the shop. It turns out he''s been swapping engines - tough job made tougher with weird wiring harness issues.  SPECIAL THANKS TO OUR SPONSORS: Wehrli Custom Fabrication WCFAB.COM Exergy Performance Exergyperformance.com Duramaxtuner.com Calibrated Power Solutions Calibratedpower.com
