John Schirado joins the podcast to talk about his participation in the Ultimate Callout Challenge 2018 as a qualifier. John knows quite a bit about drag racing in his diesel and that means he's learned quite a bit the hard way.  SPECIAL THANKS TO OUR SPONSORS: Wehrli Custom Fabrication WCFAB.COM Exergy Performance exergyperformance.com Diesel Power Magazine' trucktrend.com/diesel-power-magazine/ Calibrated Power Solutions CalibratedPower.com Duramaxtuner Duramaxtuner.com
