Rewind 3 years, if I had started with 1023 tunes I would say the medium tow tune. This would be because I would have learned how to drive the truck on those tunes and be just fine.

I really think that if I had started with 1023 and then tried another flavor of tunes like GH, I may have thought that GH sent me the wrong tunes. The truck does well on the 1023 tunes, but it does better for me on the GH tunes only because that is what I am used to.

I hope this makes sense.
It makes sense to me and that would be a common thing with a lot of things in life. Whatever you are used to is what you will stick with unless something throws you off of it. What that tells me is that they might be a little different but both are working well for you.

Here is my quick update on 1023 tunes after towing 2100 to Colorado and back.

Dusty has it figured out. It was nice to set the cruise and go.

I ran the Medium and light tune with my SXE turbo and 35 in tires towing a 10K toy hauler. I ran mostly in 3rd gear at 62 mph the whole trip. EGTs were 900 degrees on the flats and 98% of all hills being pulled were 1100 degrees or lower. Boost while pulling hills were between 15 and 20 pounds. again, all in 3rd gear. It was awesome to be able to accelerate up hills and not back out of them due to EGTs. Dusty's tunes are very predictable and made the trip that much more enjoyable.

There were 3 hills that I pulled in 2nd gear and that was due to the lack of hitting with speed and or 20 mph hair pin turns. One of these hill climbs was at 8K to 10K foot of elevation. Again, no issues.

There were a few times I tried the PHP server tow tunes and they ran 100 degrees hotter. Thank God for the ability to switch tunes on the fly.

When I got to Colorado, I sent a text to Dusty about the successful tow with his tunes. I had a shift question and he jumped on a call with me and I had a tweaked tune in less then an hour.

Like I said, Dusty has it figured out. Great job my friend and thank you!

Akcooper9, I know we have discussed this, but can you tell the other interested FTE'rs what the trucks RPM's were around 62 MPH in 3rd gear? I know where my RPM's are at, but I have stock sized tires on my truck.

As we all know, RPM/engine speed can make a big difference in the way a truck handles a heavy towing load.

Around 2200 RPMs. Highest RPMs I saw were 2400. MPG on this trip was 9.5-10.5 depending on if I was running into the wind.

A quick update to my opinions and observations on the 1023 tunes.

I asked for the "medium tow and daily drive" tune to be reworked for my own personal preferences. What I mean by that is the tune was a bit too much throttle up front for my tastes. Others may think it was just fine, but for me there was too much throttle input early on in the pedal stroke. Dusty sent me some revised tunes a couple of weeks ago and just today I had the chance to check them out while also ops checking my Torque Pro configurations to make sure everything was working as intended before moving onto Forscan Lite to get it set up.

I did not do any data logging, but will in the future before and after the SX-E install that I have going on soon.

Some readings I took with my glance-o-meter (looking at the gauges quickly while watching the road) during some near WOT (80-90% throttle) runs unloaded while going down country roads. I don't typically take my truck above ~75% throttle, but for the sake of testing the updated tunes I figured it would be OK.

- FIPW would blip just above 3.0 when going to near full throttle quickly. The highest I saw was 3.7 and that was for a split second. Most of the time FIPW was 3.0 - 2.5 when pushing the engine hard
- Boost was ~25-28 PSI
- EGT's were well below 1200, but this was unloaded and burst moments of speed

The updated tunes are much more to my liking in regards to driving style. I would say that up until about 30-40% throttle it acts a lot like a stock tune does, but then the power kicks in at a much more linear pace when going above that. I learned to drive my truck on Gear Head tunes, which act a lot like this, so when I tried the 1023 tunes mentioned above, I was having a hard time with them. If I had an automatic, I think things would have been different and I may have like the original, but with my driving style and ZF6 transmission, I prefer the way they are now.

The truck idles differently than the GH tunes. It is difficult to describe. I would not say it is louder or quieter, just a different tone coming out of the exhaust and sitting in the truck.

The truck seems to run a bit more smooth, and is definitely a bit quieter while cruising at 55 MPH or so. I recently replaced the insulator boot and gear shift boot on my truck, so some of this new found silence may have come from that too. My wife and I have no problems at all carrying on a conversation at normal volumes while running down the road at 55 MPH.

We will be going camping again in a couple of weeks and I plan to run the 1023 tune when we set out on that trip. Although, I don't have the SX-E installed yet, so I will be keeping an eye on EGT's and how hard the truck is working vs. the GH heavy tow tune that I normally use. I don't want to push it too hard, but if I feel there is too much going on with the 1023 medium tow and daily drive tune I will simply bump the Hydra down to the GH heavy tow until I get the SX-E installed.

I am very happy with the 1023 tunes since the update.
