Diesel Performance Podcast

We got back from the WCFab Open House and saw so many badass high horsepower trucks throwing down huge numbers on the dyno that it got all three of us thinking; do I really need 1,000 horsepower? The boys discuss the fun of it, what it takes to get there, and the practicality of a diesel truck that powerful. See what Anthony and Chris had to say here!

Anthony and Chris are back to tackle a topic we often get a ton of questions about: compound turbo kit or single turbo? The boys figured why not bring Nick Priegnitz, Stealth Turbos creator, back on to discuss this topic. We tackle the value of each setup, what works for certain driving styles, and a ton more. Class is in session on turbos!

We have a mid-week bonus episode! The boys wanted to get Nick Priegnitz, founder of Calibrated Power/Duramaxtuner, into the podcast to discuss what he and they think of the initial numbers and news on the 8.3L Duramax L6P "Mongoose."

You've probably seen the news; if not, we are going to discuss it in depth on this episode of the Diesel Performance Podcast.

Anthony and Chris break down all the details, what this means for the future of tuning, and much more!

Chris and Anthony have a specific topic they want to discuss today. Lately, the boys have been fielding a lot of calls and questions regarding how sluggish and underpowered a lot of these big cab & chassis Cummins, Power Stroke, and Duramax trucks are.
