3336HP and 185psi of BOOST! WORLD RECORD!

We made our way back out to the Ultimate Callout Challenge and as usual, it did NOT disappoint! Not only did the Ziegler Diesel Performance team rip off a 4 second pass (at 185psi of boost) their first pass, they made history on the dyno! We almost could not believe our eyes when we saw 3336HP after a MONSTROUS dyno pull!
