Fit like a glove
Everything worked great no problems
Easy to use
I purchased the full LM2 Delete kit that had everything I needed. The process is pretty straight forward. I do wish there were instructions to verify, but for my first delete I made it through without issue. Expect two to three days of actual work once the tune is flashed. I have increased the reliability and MPG for my truck and could not be more happy. If you have the dual center exhaust, I would recommend the PPE side exit exhaust to reduce soot on the back of your truck.
Easy to use
Excelent service
EVERY THING WENT GREAT THE FIRST TIME
Great product!
200% worth it
The turbo spool is much quicker, and the power increase is insane! Its getting better mileage but not exactly how much better yet. The problem is with the additional power I can't keep my foot out of it, So getting true mileage reading is tricky. Driving to Montana soon and that will give me a accurate reading. Will advise. Thank you Mike
So not sure why I got two boxes one day and yesterday got a long box @930 at night. Get a call from my shop after they got 95% done and they ask me where was the egr delete kit was? I didn’t open the box but assumed everything would have been there . Nope it got shipped yesterday and sitting with DLH in concord Nc … just really not a happy camper at this point
Very easy to navigate and I had a little trouble getting the tune to take to the ecm but customer support helped me through it
The 3.0 Duramax delete itself works great on my 2020 Silverado no more DEF system headaches, and the turbo spools faster. Instructions were a little vague for wiring the EGR block-off had to call their support line but they walked me through it. Great product and tunes so far.
GM Duramax LM2 All-In-One DPF/DEF/EGR Delete Kit (2020-2022)
Tried the 3.0 Duramax delete kit for my 2021 Sierra for my 21 Sierra was sick of dealing with constant regens and limp mode. Took the weekend to throw it on and the truck woke up. No more DPF junk clogging it up, throttle feels way snappier and Im getting 3+ MPG better on the highway. I highly recommend.
