Thanks for your info, I'm going to look into Linear Logic Scan Gauge II. I have HPT but I don't see using it with a laptop as a viable option for 'quick' checks of temps on the fly. I only have a couple of days of data with the new setup. These numbers are all from the same route on my 24 mile trip to work, 95% of the trip is highway (half at 70 mph, half at 60 mph). The average air temperature has been 40 degrees, the modified transmission temperature (from the dic) average is 123 degrees. Before the mods, on the same trip, it was: Average air temperature was 38.5 degrees, the transmission temperature (from the dic) average was 168.9 degrees. I'm thinking that my modified trans temps are so low because on the 2018's, the transmission cooler is part of the AC condenser, and not the radiator. So the engine temperature is not helping the transmission warm up. My main reason for my mods is to help lower my temps while towing, which I will be testing this weekend. I'm pretty sure I will have the desired outcome, but now I may need to adjust the temps (ie: 140-160 degree trans thermostat) for my daily driving.

Mr Bear, When you post your temperature figures, are you using the factory gauges or are you using some other type of scanner? I just finished installing the 197° thermostat. I also deleted my transmission thermostat and installed an external transmission spin on filter. I also modified my tune to turn on my fans at a lower temp (used JonA's tuning suggestion). Using my factory gauges, my water temp is still sitting just below 210°. My factory transmission gauge clearly shows lower temps than before. Since I live in Denver, I do plan on installing a 160° transmission thermostat before winter.
Oh I agree! Full disclosure: I'm using an Elite Engineering E2 catch can and clean side separator. I am amazed that this catch can collects more on my 5.3 Silverado than it did on my supercharged 3.6 in my Canyon.
Do you have any concerns with running your ProCharger in such cold weather? I had one on my 2015 Canyon and ProCharger had a warning in the install instructions to not use the procharger in temperatures below freezing. From what I learned, ProCharger had experienced failures in extreme cold, apparently the different metals (aluminum housing and steel impeller) expand and contract at different rates in the cold. The warning may have just been a way for ProCharger to avoid paying out warranty claims for folks in the north that beat too hard on them in the cold. I ended up removing my ProCharger and selling my Canyon. But after watching your videos, I am tempted to install it on my 2018 Silverado.
Long story short, I'm replacing my 5200 pound (fully loaded) travel trailer with a new, larger camper. But I'm having a hard time convincing myself that my truck can handle (comfortably) a 6200 pound (dry) camper. Forgot to add: I currently use, and will continue to use, a weight distribution hitch. My truck: 2018 1500 CrewCab short box, 4x4, 5.3 with 6 speed, tow package (not max tow). 9100 pound tow capacity. I have the Chevrolet Performance Air Cleaner and the Trifecta Elite tune. I live outside Denver and tow my camper approximately twice a month in the mountains or Wyoming, 8 months of the year. It would be helpful to me if you could post up the specs of your truck, the weight of what you tow, how often you tow and what part of the Country you live in. Also, before anyone suggests it, I realize and 2500 would be a better towing truck, but it is not in the cards for me right now. Thanks in advance!
The Airbox mod is simply enlarging the hole in the side of the airbox where it goes into the inner fender. The fender has a large hole stamped out of it, the stock air box for the 5.3 has a small hole. I believe the stock airbox for the 6.2 has a larger intake hole to match the fender opening. I know the GM Performance air intake utilizes the entire opening in the fender.
I have the Trifecta Elite tune for my 2018 and I love it. You buy the tune from them and download it onto your laptop, and they send you a obd-II cable. Once you have the cable, you can load the tune from you laptop. You can also go back to stock as the loader saves a copy of your factory tune. I currently have the tune loaded that disables the AFM when it's in Sport mode. My favorite feature of the Trifecta tune is that it has 2 different modes that you can change on the fly, Eco and Sport. I drive 95% in Eco mode and only use Sport mode when I want to break the tires loose. https://www.trifectaperformance.com/forums/store/product/2202-2014-2018-chevrolet-silverado-53l-elite/
I just installed the GM Performance Cold Air kit and it is louder. It seems that my noise is coming from the front passenger fender area, it sounds like more air moving through it. I am a little surprised as it is louder than I expected.
