I don't have a full review as of yet as I only drove it from the shop to my house last night which was maybe 15 miles all hwy.  I can tell you that it feels like a completely different truck.  It moves absolutely effortlessly.  They weren't able to calibrate the new gear ratio in my tuner (I suspect because the battery was low) so I didn't know my actual speed and couldn't verify it with GPS because my son was in the back seat on my phone playing games.  I was going with the flow of traffic on a 70mph hwy and my speedo was reading 89mph.  My guess is at 70mph my rpms were right at 2000rpm.  I'll have more info on that later today after I get everything synced with my tuner.  I can confirm though that with the ecm not knowing the new ratio I didn't get a check engine light.  Mechanic says some do it and some don't.  But the tranny doesn't like not knowing the ratio for sure because it short shifts real bad.  Truck maintained 6th the entire way home where as before on the slightest incline it would down shift.  It doesn't do that anymore.  With the rpms being up higher, the slightest throttle input just makes the truck go.  Its really pretty sweet.  Like I said Ive only driven it maybe 15 miles but can tell you its worth every penny paid.  I cant wait to hook up to my toy hauler and see how it tows.  I have to baby it for 500 miles before I do any towing so I'll post up about that eventually

What tuner do you have?

Did you get the calibration problems resolved?

Intune i3

 

Yes I got it resolved.  Giving everything a good 500 miles to get broken in and waiting to see if the trans settles in.  The custom tune I have for the trans Im not really feeling right now and think after the gear swap the stock trans tuning is better.  Gonna see if it works itself out or if I need to go back to Lew to have him fix it.

Can you get me a picture with the Cruse control set at 75 mph once you have it calibrated so I can compare it to geswek

I’ve gotten my speedo calibrated and at 75 I’m at the notch just above the 2000rpm mark. So I guess that’s 2200-2300rpm

 

my cruise control isn’t working right now because I have a wheel speed sensor out. I’m replacing it this weekend. After I get it fixed I’ll get a pic

I wish you weren't a world and a country away or I would try to buy your 3.42's off of you. Would be all the help my 6.2L needs with her fat, heavy diesel tires.

Sorry to bug......but can you get one with the MPG showing at 75

I do most my driving in the city because I work from home so I don’t ever really go any where. The 14.9 best is up from mid 11’s so that’s quite an improvement. Running flat on the hwy at 75 and it hovers right in the 20-21 range.  Not bad for a 7” lift on 35’s

Wow!!! Thats impressive.  

Do you have enough miles to give us a review?  How does the truck like 1st gear? Does it actually pull through it or shift into 2nd right away?

 

6.2L  or 5.7L ?

 

Thanks for all the help and info by the way ?

Its just flat out better that's about the best review I can give.  1st gear is fine.  With moderate throttle it will hold all the way to 2500-3000rpm before it shifts.  The rest of the gears shift a little early but I can understand how the gearing would make the tranny want to get to 6th a fast as it can.  Its not bad, I wouldn't say its short shifting or anything like that.  Shifts are around the 1800-2000 mark.  If I stomp on it, it will rev almost to 6000rpm before it shifts from 1st and carry the rest of the gears well into the 5000rpm range.  Im gonna send a WOT log to Lew and see if he changes up the trans tuning at all. 

 

IMO it feels more diesel like to me.  It takes a bit of throttle to kick down a gear more now than before.  For instance going up a hill and giving it a good amount of throttle, a diesel will just power up it in whatever gear its in.  My truck is much more like that now.  Whereas before it had no issues downshifting 1-2 gears if need be.  Before my truck couldn't maintain 75 in 6th gear for any amount of time.  At the slightest incline it would downshift to 5th and was constantly hunting gears.  That's a thing of the past now.  I was pulling my 18' flatbed trailer yesterday taking one of my atv's to get serviced (probably a little over 3000lbs) and had the wife and 3 kids in tow and once on the hwy the truck didn't get out of 6th the entire trip and I was passing people right and left.  It just pulls and pulls hard and does it with minimal throttle. 

Gas mileage has gone up as I mentioned before.  I was getting between 225-250 miles to a tank of gas before and now Im getting over 300 and that's mostly with city driving and occasional hwy. 

 

I have a 5.3L  

 

I'll get some short vids in the next day or two running it through the gears so you can see what its doing

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      By Grumpy Bear · Posted

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
