EGR Filter System for GMC/Chevrolet 6.6 Duramax 2020-2025

We'll have full deletes and tunes soon enough. There'll be no enforcement of any of these problematic emissions crap soon enough. You'll just have to get a clean tune so you ain't puking out soot on your gear!

Has anyone tuned one of these? I wonder how much it is to unlock the computer and TCU for HPtuners.
 
It looks like the computer requires 8 credits which is $400. The you have to have it unlocked before you can program it which is another 600-1400. That doesnt include the tcm.

HP Tuners has not cracked the code on the 24+ rigs. That's the new Global B computer architecture. I think tunes and the tuning interface tool is gonna run at least $2500. Duramax Tuner told me it would likely need a tool like Edge to load and run.
 
I just yanked my fass egr filter off a few days ago. The clamp upstream of the filter came loose 2 months after install and I fought it for a week but couldn’t get the surfaces mated up properly. Finally pulled the filter out to really inspect everything and the “clean side” pipe was just as filthy as the dirty side. Decided it was snake oil and put the oem pipe back in. Immediately noticed less engine vibration. Do not recommend, but if you want to take a crack at it I’ll give you a hell of a deal on it LOL

One of the things to keep in mind with the EGR, is that it does reduce cylinder temps by introducing cooler air. So any changes typically require tuning to be effective.

The problem with these emissions systems, is they were designed to function as a total unit. If you make changes, you usually have to address the whole system. At least some tuning is required.

That's why I think you need an emissions intact tune like Duramax Tuner, or a full delete and clean tune. Not sure I like the in between solutions for that reason.

How much HP does it increase? I don't know that much it's my 1st. Diesel a friend always talks about the delete kit. Increasing the turbo.

You can't delete or increase HP without proper tuning. Right now HP Tuners is still trying to crack the code on the locked down Global B software architecture that came with the 24+ models. Until that happens it probably doesn't help much to add or swap parts.

There are currently a couple options to add 50-60 HP, but they are not tunes, they are just fooling the fueling system to make the gains.

Once tunes become available, expect them to be pricey. I think $1500 will be low end but won't be suprised to see them at $2000-2500.

What about the pre-24 gas 6.2L trucks? Do they have similar Global B software? Are there any tuners for the 2022 - 6.2L V8's?

So is this a delete kit? Def delete

Not a delete it’s an aftermarket filter between your exhaust and egr. No performance gains it’s just supposed to catch soot and burn it off before making it back to the engine. In a world where deletes are illegal and unavailable this would be a great solution to keeping your engine healthy for the long haul, but from my experience with it I don’t believe it to actually do anything and as to Axe’s point we will have deletes soon enough which is the ultimate solution.

Wow! Don't need a tuner that bad.

Cost of entry is high but gains are pretty significant. 50-60 under the curve and 25-30 peak.

VVT does very well when tuned for 93.

Full exhaust and tune should place the L86/87 around 500 crank.

Nothing off the shelf that I'm aware of! I mean like from the usual big name tuners selling handheld or LCD screen devices to reflash the ECU.

500hp at the crank sounds great, but with the cost of an exhaust plus the cost of a tune from HP Tuners, is it really worth it?

$20-30 per HP? Most accessories aren't worth it, but they make for a better experience if that's what you're after.
