2011 - 2016 LML Duramax 2500 3500 4500 5500 | HP Tuners

Runs great has good power and smooth shifting with excellent pedal response with no falloff

Super fast service and support. Drew had my 2015 Duramax up running same day. When i get my second truck i will be back. Would and Will recommend

Couldn't be happier with everything! The team at TWD was easy to work with and puts out a fantastic product. They'll be getting all of my business for anything diesel from here on out!
