The guys feom 1320video made their 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!

These guys almost could not believe their eyes when they saw 3336HP after a MONSTROUS dyno pull! That’s just crazy! Just watch the video below to see the action and share this one also with your friends and follow us also on Facebook, Pinterest or Instagram!
