"In Relentless Pursuit of Performance"

  [ Online Forum | Videos | Dyno ]

We are a full service diesel performance shop located in Willis, Texas.  We specialize in engine and transmission work on Cummins and Duramax equipped vehicles.  If it's related to engine or transmission repair or upgrades we do it.  That includes custom tuned ECMs, programmers, exhausts, turbocharger upgrades, camshaft upgrades, engine rebuilds, automatic transmission rebuilds and upgrades.  We've built 1000 HP racing engines as well as work trucks that need more power without losing reliability. 

We are one of the few diesel performance shops with an in-house Dyno.  Our dyno is specially calibrated to read up to 2500 ft-lbs of torque!  If you want to know how much power your rig REALLY puts down either before or after upgrades we can do it.

We handle a wide variety of products including:

  • Chips, Boxes, Programmers
  • Modified Injectors
  • High flow Intake Filters
  • High Flow Exhaust
  • Upgraded camshafts and valvesprings
  • Custom Heavy Duty Transmissions
  • Turbocharger upgrades
  • Heavy duty Clutches

We Do It ALL!
