Turbo Core Charge:

The LLY Promax is basically your stock turbocharger on steroids. Built specifically for the 2004.5-2006 LLY Duramax, this turbo is perfect for the 400-625rwhp market looking for better EGT control with a much broader power and torque band to work with. This turbocharger is a direct replacement to the stock unit, with no other changes to the truck required. Improved air flow from our 63.5mm 7-blade FMW compressor wheel along with a high flow 10-blade turbine wheel for better drive pressure control without sacrificing spool-up makes this the ultimate bolt-in upgrade.

Built transmsision, EFI Live tuning and a lift pump will help reach it's maximum potential.

ProMax Upgrades

Our popular ProMax and ProRam line-up of modified stock turbochargers are getting an upgrade! After extensive testing on the bench, the street and on the dyno, we are happy to announce we are upgrading to a true performer with an all-new 63.5mm 7-blade Forged Mill Wheel. This wheel design offers better durability than standard billet wheels, along with a broader power and torque curve to make your daily driving and towing tasks even easier.

  • Forged Mill Wheels offer better strength than standard billet wheels
  • 7-blade design for broader, flatter power/torque curve
  • Better spool-up and response for better smoke control
  • Cooler EGT’s throughout the RPM range
  • Available Compressor Flow Map, does the competitions wheel offer that?
  • Proven performance for your daily driver

To go along with this all new FMW compressor wheel, our ProMax turbochargers also offer high flow 10-blade turbine wheels to reduce exhaust back pressure and EGT’s under load without affecting drivability. With 360-degree thrust bearings standard and a full one-year warranty, your truck will never be so happy to make boost again.
