Customer photo review of GM Duramax L5P All-In-One DPF/DEF/EGR Delete Kit (2017-2025)

Tuner depot was very helpful I thought I screwed up on the tune part and flashing the ecm but there customer service told me I didn’t mess it up and helped me through it but one thing for sure is nothing to do with tuner depot but no one every tells you on a first time doing one of these trucks the amount of hours it takes it took me almost 30 hours which if I had the right tools and confidence I could of probably cut it down to about 20 but kit works great it’s got awesome power now and I’ll be doing the down pipe very soon to I highly recommend just buying it and getting it over with because the truck is still very quiet almost like it’s a notch above stock

Customer photo review of GM Duramax L5P Cat & DPF Delete Pipe (2017-2025)

I purchased the efi live sotf tunes along with Dpf delete kit, dpf was good quality, tuner worked with me and not only sent my autocal loaded with a sotf tune but also sent me a few single tunes to use until I installed the switch, the only negative was that 130hp was the max power tune single or switch on the fly, but over all I was pretty happy and service was very good throughout.

Could have come with some kind of directions. Made it through it ok but a little direction would have been nice. Overall everything works as it should.

GM Duramax L5P CAN BUS Plug Kit (2017-2023)

Before installing never had a code after install getting low fuel rail pressure code under load. If I keep RPMs up just a little ( by switching to manual shift and never come out of 5 gear Allison 6 speed trans) will work fine . If u shift to 6th gear lower RPM as soon as u go up a little incline it starves for fuel and goes into reduced power mode. But if u mash the excelsior and down shifts it will take off like a rocket.

SOTF Switch for GM Duramax (2001-2023)

Muffler has great sound, no restrictions. The best part of the whole deal was the outstanding service and shipping that Tuner Depot provided. Would definitely use them again.

Nice mellow tone and quiet, no diesel is quiet but this muffler makes trips comfortable with no throwing noise at highway speeds.
