2017 - 2023 L5P Duramax 2500 3500 | Pickup and Cab Chassis | HP Tuners

Hit them up and right away they took care of me, answered all my questions and I had a lot of them from start to finish. Truck runs better then before ecm and tcm tune, exceeded my expectations. I will be using them again and will be sending everyone I know to them.

My truck has been tuned for a while, I started having a lot of issues and I narrowed it down to my tune. So I had someone put a tune in, they used starlite I believe. Also while this “diesel guy” had it I wanted a new turbo. All for 5200k After he swapped them he couldn’t get it to relearn. So I went to buy an actuator another 1000$ and he still couldn’t learn it! So I brought my icon t8 and learned it in 5 seconds. Started driving home check engine came on for speed sensor. He told his tune people and sent another tune. Well still didn’t fix it. Then tells me he gave them wrong tire size! They sent one with correct size and still didn’t fix it. Limp mode I drove home and ordered tunes from yall and as soon as I wrote it to the truck, completely fine!! Been driving it every day and no problems at all!

Fast and easy and will work with you if needed
