If your ecm is tuned from another company, the flash won’t work. IIRC.

I think there’s a lot of tension and frustration when it comes to comparing what tune to get and a lot of backlash from others when someone speaks their mind about the opinion of what tune is better. No matter what, the truck needs a tune to expect any sort of life span i believe. One person...

Went with SKT based off of availability and ease of tuning when I want. That being said If anyone wants to give me tunes from other people to review I’d be more than willing 🙃

I purchased one from eBay for 100$. Deleted my egr tube just fine. I haven’t had time to completely delete the death valve yet.

UPDATE Approaching the 2500 mile mark tuned. All is well so far. I keep getting a nuisance p04DB when I tow. Also got it the other day on a straight away. It appears my rpms go too low for more than 2 seconds and it trips. If I tow in manual mode I’m fine. I DO NOT ATTRIBUTE THIS CODE TO THE...

I haven’t seen a motor that doesn’t have an issue. Google around you’ll see new and used Cummins and duramax and p strokes in shops for issues.

Got mine at 113k deleted egr at 133k. So far all stock motor excluding intake plentum and egr previous owner did at 109k per service records. It’s all a lottery when you buy used.

Egr delete seems to be number 1. Tune it. Dpf/scr delete if desired, and dealer told me don’t go over 7k on oil changes. 8k only if you absolutely need to.

I remember reading somewhere the mufflers were the same for the 3.0 and the 5.7 that’s why they mass produced the straight pipe. I’ll look today if I get some time at work

My dealer in va told me to go to an actual diesel shop 😂😂

Matt I did install the diffuser tube blank offs but my egr is still in place. You can get muffler delete from amazon along with dpf straight pipe for your testing purposes

UPDATE. Kept getting a reoccurring p04DB code From time to time since I switched to 35’s. I reset shift values in my trans tune and boom seems to have improved my shifts and truck is even more responsive! I’m curious to see if the truck throws it when I pull trailers anymore.

Did they diagnose what caused it? Drivers side iirc the only thing that stood out when I popped my hood was the oil filter

Need computer for initial setup and internet to send stock file and receive tuned files

Yeah remove it.

This is how I find my regen level. Once it hits 70 it jumps to 100 and eventually will regen.

ODD DISCOVERY/ OBSERVATION Hey everyone! I’m enjoying my SKT so far but the other morning and one of my very first mornings with SKT I had an odd scenario occur. The following conditions were present: 1. Cold as balls (under 20 degrees F on the evic) 2. Block heater not plugged in. 3. Truck...

UPDATE Had to go rescue a Toyota today... pulled the trailer 25 miles to him and 25 miles back and evic is averaging 17.9 still!!

I believe the previous owner did a lot of across state driving mixed with gridlock traffic or something. I can’t recall what it had when I bought it.

We have discussed how many miles on our trucks... But a quick forum search turned up nothing for engine hours. Currently I have 507 idle 3298 driving 3805 total As people have related miles to a motor, I feel hours are just as equal in the equations when discussing bearing failure, egr leaks...
