With the L5P being the newest Duramax engine on the scene it's also one of the best performing right out of the box. Making 400hp and 850 ft-lbs of torque when tested on our dyno. This iteration of the Duramax engine has been redesigned in all the right ways. From a thicker crank shaft, to a more advanced turbo, and pistons that can handle more load and heat than we've ever seen come in a stock Duramax engine before. Not only do we get improved performance but we also get an engine that can handle way more power than it left the factory with. Which means with bolt on upgrades alone you can raise the horsepower way beyond stock without having to do any upgrades to the internals of the engine. We've seen L5P's pushing up to 900ph on the stock internals. Even trucks still equipped with emissions systems can gain about 300hp and 500ft-lbs of torque with just a few bolt on upgrades. Today we will show you what upgrades you want on your L5P to make the biggest difference for the least about of money. So if maximum performance is what you’re looking to get out of your L5P this article is for you.

 

Here are the top four L5P upgrades!

  • Tune
  • Transmission
  • Turbo
  • Intake

How does Allison 1000 TCM Tuning help with towing?

TCM Tuning is the modification to the programming calibration of a Transmission Control Module (TCM).  Ever since 2001 when the Duramax was first offered in the 2500 and 3500 GMC and Chevy  HD truck it has been paired with the Allison 1000 transmission. 

These trucks are designed for towing and if you use it that way, you can probably think of a few ways you would like your transmission to act differently.  That is where TCM Tuning may be able to help.

Common Complaints About Stock Transmission Tuning:

  • "When I try to pass and I am in 6th gear, it is very reluctant to downshift."
  • "While merging on the express way it seemed to take a long time to get from one gear to the next. It's even worse with a trailer on."
  • "Even with tow haul mode on the truck doesn't seem to shift well since I put these larger tires on."
