He walks the boys through how he accomplished it and what you can expect to see out of him in the future.

Chris Ehmke is joined by the lead tuner at Calibrated Power, Tim Mahoney, to discuss how the 2020+ Powerstroke 6.7 liter world is about to change.

Show favorite, Chris Patterson, owner of Unrivaled Diesel, took second at the Ultimate Callout Challenge 2025!

You have to see Patrick Brown's Cummins he is bringing to his first run at the UCC event. Chris sat down and talked with him about what he expects to see it do. Patrick is no stranger to competitions with having his eyes one time set on the Diesel Power Challenge nd having competed at King Of The Streets, he's ready to throw down at the UCC. Humble, determined, and doing wild things with such a cool Cummins, we are stoked to see what Patrick accomplishes this weekend!

One of the show's favorites is back, Robby Garcia joins Chris to discuss what he expects of his truck at this years UCC! This will be his 4th time competiting, a seasoned vet, and continually improving his results; these factors position Robby to finish quite high this year. One thing we know will happen, Robby will have a blast and bring that vibe to the whole field. Good luck, Robby!

Cody Hawk sits down with Chris on this episode! We get the scoop on the new competitor, from his roots with 7.3s to his preferred Duramax platform. He breaks down what he wants to see out of his truck at his first event. The man is in hustle mode and it's hard not to admire the drive and work ethic. Last year two spots on the podium were grabbed by rookies, will Cody continue the trend? We hope so, good luck Cody!

Chris has Mike Brown on this episode! Mike has ditched the mega cab in favor of a leaner regular cab, will it push him to the top? Mike left last year's UCC finishing third in his inaugural run at the competition. New Cummins, big win? We are excited to find out. Thanks for joining the show, Mike!
