Yep, agree. Seems way too complex. It has a lot of new this and that to pass EPA and get good mileage.  Not a first year engine buy for sure. IF one gets one, one better get 100,000 mile power train wty. . 

 

6.2 seems a better choice right now. .

Two chains AND a belt on the rear of the block??? That sound like a very expensive maintenance bill. Second, I wonder if the ECM is going to be encrypted like the 19 Colorado DMax and the upcoming C8. 

 

I was waiting for this engine also, but starting to lean back towards 6.2

He said that the chains don’t need to be touched and the belt is serviced by backing the trans off a little and removing a plate not very hard. At 150k the min you could run the belt longer her said but 150 is recommended.

Did yall watch the 14 minute engine vid walk through? If that does not strike one as complex, with a lot of valves and sensors and water flow here and there based on this and that, I do not know what will.  As one that had the early model 5.3 with the new AFM issues, the 6.2 looks like the way to go for a few years at least. 

 

Edit: 6.2, even with the new DFM, still seems like a better choice. At least there will be a DFM deletion kit soon, should it give one issues after warranty.

So the 3.0 has been out for a couple of years now. I just bought a 21 AT4 with the 3.0 duramax. I'm wondering if any of you have found any mods to do to make a bit more power WITHOUT voiding warranty? Dont get me wrong, I'm very impressed with the little i6 duramax! But, being a guy who is always looking for ways to improve things, I was curious as to what anyone has found out! Normally I wouldn't ask for things like this but I havent had the balls to tear into it myself!

Intakes and inline fuel pressure modules is about all you're gona find. There's other threads on here that discuss these. And both of those will give you a bump in power and throttle response. Exhaust won't make any difference since its straight pipe after the cat.

Agreed, aFe and S&B make intakes. I'm looking to get the S&B intake soon for my 3.0. Also looking into the fuel filter mod. Other than that, the EPA has really killed the diesel tuning industry. There are guys on here that have replaced some of the hoses and what not, but not much in the way of gains.

 

Banks has their PedalMaster, looks promising, but it's just a piggyback tuner, people say their butt dyno says there's more power. I never trust the butt dyno as I feel it's more of a wallet dyno. As in, "I spent money expecting more power, so therefore I feel more power."

 

All in all I didn't buy my baby-max for drag racing. It's actually plenty fast off the line, sure it doesn't have top end power, but that's not why I bought it.

The Banks PedalMonster isn't a tuner, it is a throttle booster. I have one and like it. It removes the delay in the throttle so it feels more like a cable operated throttle. There are numerous levels you can set it to to dial it in to your liking. It does nothing for performance obviously. It is just for improving throttle response.

 

The Banks Derringer is their piggyback tuner, but it hasn't been released yet. I've seen estimated gains directly from Banks indicating they expect to see 60+ HP and 110+ lb/ft increase at the maximum setting. I'll be first in line when they are available!

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.

      They’re not the same wiz as 10-15 years ago.  QC has fallen pretty hard.  The XP line was never good though in the first place.    https://bobistheoilguy.com/forums/threads/wix-filter-rusted-through.386492/post-6991372   https://bobistheoilguy.com/forums/threads/i-ve-used-my-last-wix-filter.27299/   https://bobistheoilguy.com/forums/threads/looking-for-a-better-replacement-for-wix-51258.403977/   https://bobistheoilguy.com/forums/threads/convince-me-in-using-the-purolator-boss.401537/post-7420147   the forums are littered with posts and examples of not great wix filters the last couple years

      I'd guess that it's because they are Mann-Hummel filters since about 2016, they own Wix and are mostly all made in China now.
