Got my BlackBear tune installed on Saturday & as was expected, my SES light came on & I needed the crank relearn. Justin had sent some detailed instructions on what to do & how to install the tune. Rather than having to pay someone $85 or so to do the relearn, the software Justin sent with the scan cable was able to do it. After warming the truck to normal operating temperature, I followed his instructions for the relearn & within seconds, the relearn was done & the SES light went off & the truck was purring like a kitten...nice & smooth!

 

Took it for a ride & was surprised at the difference! Under light acceleration as in daily driving, the truck moves effortlessly & not like something was weighing it down as it did before. Shifts are firmer, without the small lag after shifts, but not bone jarring. It is a constant pull now through all the gears.

 

The only WOT run I did was from a roll of about 25-30 mph. HOLY SHEEIIIITTTT! It pinned me in my seat & flew! It down shifted quickly & pulled REALLY HARD through all the gears until I finally let off it a few seconds later at about 90 mph, at which point, it was still pulling & accelerating hard!

 

I can't wait to get my boat out of the shop so I can try it towing...if the regular side of the tune is any indication of the towing side of it...it should tow ALOT better!

 

I will post back in about a week on how my mileage is going...hoping for a little improvement there also!

 

For those wondering, I told Justin I am running only 87 octane & was not interested in turning my 4.8 truck into a hot rod. I just told him I wanted optimal performance & wanted the tow/haul button to be kept for towing since I tow my bass boat on weekends.

 

To me, the fact that his software & scan cable he sends out allows him to see exactly what your PCM is doing before he makes any changes makes the BlackBear tune the way to go! Plus the fact that I was able to do the relearn right on the spot without having to find a dealer or someone with a scanner & pay close to another $100 to have it done!

congrats! i believe that justin left your tow haul button stock. in other words there will be no performance gain from using your tow haul button. when you activate it you simply will return to the stock trans and fuel trim settings for the tow haul button. this is what he suggested when i did my tune.

The engine changes are still there in tow/haul mode. The tow/haul button affects shift points, TCC settings, and shift pressures.

 

With those settings left relatively stock, the shift patterns will be the same as they were before the tune, but the power gains should be just the same.

      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.

      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.
