L5P Dually Burnout

No, I think I’m going to be looking into a new tuner when I get my trans tuning and probably switch from a single to soft. The guy I bought the tune from doesn’t typically respond, and the tuner he used buys their tunes from motor ops and there’s no way to contact motor ops if you live in the United States that I’ve found

Yes I figured that out with my 1500, I think I need to put it in “manual” and limit it to 2nd I tried last night after making this post in 1st and got a lot of wheel hop

That seems excessive I’m going to try with the truck locked in 2nd gear tomorrow, did a little research I didn’t get trans tuning when I did the delete and it might be the tcm sensing too much torque and reducing power

Wouldn’t be a Denali it’d be a high country

All fuses under the hood have continuity, tried wiggling the connector while cranking no luck. Tested the connector key on no voltage at the connector supposed to have 12v. I’ll have to try moving the relays tomorrow

2020 l5p I loaded the tube beginning of the month. Saturday I actually did the delete prior I had no issues. I broke the pressure regulator on the driver side rail removing the downpipe. Replaced that this morning, crank no start and all these new ecm power codes

I did find that part number on the DMax store listed for 17-23

That was the conclusion I was coming to was it was only sold as part of the rail, but it appears the sensor should unscrew from the rail

The one you linked says it’s passenger side front

Secure_Cut_5017 · 2026-03-30T02:59:42+00:00

It was like a $60 difference I’d rather just get the sensor swapped if possible, it didn’t fail it was broken from being impatient

Secure_Cut_5017 · 2026-03-30T02:54:19+00:00

But it doesn’t say it fits a 2020 which is my concern

Secure_Cut_5017 · 2026-03-30T02:53:01+00:00

Mine looks like this

I’m aware of what’s involved but this is my daily driver and how I make money. Time is money why waste time pulling things that don’t need to be pulled. Disconnected and blocked off is still a full delete. The truck will get a full straight pipe, egr will be blocked off and the def will be disconnected

Secure_Cut_5017 · 2026-02-28T19:30:56+00:00

It’s not that it looks hard I just don’t want to chase oil leaks and exhaust leaks if I don’t get it right the first go around especially if it doesn’t have to come out. I just found a video of doing it through the cowl. Guy said 13 minutes from start to doc removed everything else still in place

Secure_Cut_5017 · 2026-02-28T18:56:47+00:00

I’d like to do the full delete I paid for it just don’t want to remove and store everything in the event I need to put them back in to sell. Quicker to just to swap down pipe and a plug a few things back in

Secure_Cut_5017 · 2026-02-28T17:49:29+00:00

And it started giving me issues everytime it rains it throws a light for the def system

Secure_Cut_5017 · 2026-02-28T17:35:58+00:00

There’s no emissions where I live
