This 2020 L5P Duramax Gets A LOT LOUDER!

[@50calprepper]

If you guys do your own truck.. listen to what he is saying about the heater core lines! I did my 19 when it only had 3900 miles. Those fittings are tight! And the tubes on the heater core are very fragile. I actually felt my tube move! Heart went into stomach and just knew it was going to leak! Luckily it didn’t and still hasn’t yet 🙏

[@kylechew7127]

I hit mine with a little heat and the slid on like butter . No leaks .

Nice job. Love the exhaust rap on the down pipe.

Noticed the Colorado on your page is that a baby Duramax? Any content for the 2.8?

[@taylorchastain6321]

Hey man I now have under 1000 miles till my warranty is up. I’m am going to start ordering all the parts after this weeks paycheck. I definitely might be emailing you a few questions.

[@DennyDiesel]

Hit me man I can get you everything you need

[@bryanfriesen5744]

This truck only has a dpf delete right? Just a new exhaust, right?

[@mikethetoolman8776]

worm clamps on plastic parts are not going to last, that is why constant tension clamps are used on plastic parts. buy a oetiker clamp kit to use

[@brandondubose439]

Will getting an aftermarket down pipe make it louder? If someone was to just straight pioe if from dof back and leave factory down pipe?

[@jakealderman2169]

Yes. kzbin.info/www/bejne/h4u5ZplogpiFp9Esi=IrhxGHaO3BwJXfZF

[@HabibiGolf]

Hey Denny!! Anyway you can do the delete and tune with no smoke?? I'm in Cali :(

[@victoroliveira3256]

Hi Denny great video my man as per usual, I’ve been hearing rumours about the tuning becoming way cheaper in the next few months, have you heard anything about this? I was told this by duramax tuner......hopefully there’s some truth behind that, keep up the fantastic work we appreciate it.

[@DennyDiesel]

thanks man just happened actually

[@jamesgatton980]

Can u do my truck?

[@Januch009]

What did you do with the coolant return line on the turbo? Did it get re routed back to the bottle?

[@Two_skoops]

Dude I have the same question as you. In fact, the instructions I got from GDP seem to be a little different than what I have to do on my 22.

[@Srtcuz]

I have the exact same truck, my first diesel. The truck is awesome! I just had my first cold weather start a couple days ago, sounds great on high idle.

[@l5palaskan617]

I'm getting ready to do a ecm swap, downpipe /egr fix/exhaust. I got the mpvi2 , do I need that gm scanner also?

If you want your remote start back I can rent you mine out shoot me a message

[@racingasfalt8992]

I have a 22 HD l5p and i ran it low on fuel , changed the filter refilled purrged it ,and have a crank for like 30 sec but no start . Done it like 60 times. I can't find any vids or info , dealers like 3 weeks out . Dies anyone know what it may be or any site that has info

[@korn111685]

WTF? Deleting the undeleteable L5P?

[@DennyDiesel]

lol

[@davewilliams4296]

Hey bud great job I have a custom performance shop in MI what’s the name of that GM tuner box you have? I have a solas legacy and would be interested in getting the tuner you were using also Thnx

[@DennyDiesel]

hey man mdi2

[@davewilliams4296]

Denny Diesel I have a few customers with L5Ps that want full deletes done do you have any information on how I can do this in my state of MI ?

[@towtruckaj]

@@davewilliams4296 Legally you can't, And i'd be very careful with it too because the EPA cares a whole lot more about businesses deleting vehicles than people just doing it to their own private vehicles, And they can hit you with some very hefty fines...

[@kyle8380]

Don't you have to pay for a subscription to use the mdi2?

[@sparkone007]

Hey dose your truck have the thumping at Idle? That is annoying.
