it's nearly impossible to find a new vehicle with a CD player anymore.

Changing trans fluid on the 8-speeds isn't as easy and straightforward as it was on older transmissions. Like totally different and requires a computer to finish the procedure correctly or it might shift like shit.

I was talking about the Tundra. The GM trucks have had a boxed frame since 2007. The GM trucks ride firm because they have a relatively low curb weight and a high GVWR. Good for hauling heavy payloads and towing but generally ride firm. Big heavy tires will make the ride worse due to the increased unsprung weight. For what it's worth, my 2019 rides better than my 2014 did.

That delayed throttle response was without a doubt due to GM tuning the trucks to meet CAFE fuel economy and emissions requirements. Valve timing was tuned to have minimal emissions while idling but made it gutless off the line. The delay when you would give it gas was to avoid a fuel economy destroying downshift when accelerating, because the EPA highway test requires that the vehicle does many speed changes (for example, accelerating moderately aggressively from 45 mph to 70 mph). GM tuned the trucks to hold gears as long as possible. With the boosted efficiency thanks to DFM and widely available 8-speed, they had more breathing room to make the tune more aggressive, as well as add a sport mode that gives the truck a very responsive throttle and a transmission that's more eager to down shift and stay in a lower gear instead of upshifting as soon as possible. There's a world of difference between the two generations of the trucks.

That's all you're getting? I'm easily pulling down 24-26 mpg highway, verified with hand calculated MPG numbers. The new trucks have way more repsonsiveness and off the line acceleration than a tuned 14-18 truck. Especially in sport mode.

I had looked for options when I still had my 2014. The best options are either the Moog Problem Solvers or the Mevotech Terrain Tough outer TRE's. Personally I liked the attention to detail on the Mevotech ones because they have the metal reinforcement clips on the boot to keep water out and grease in, and there's a one-way valve in the boot that lets old grease push out of the boot when you pump new grease in, so you don't have to worry about overgreasing them and blowing a boot out.

Nope 22 PSI is the bypass pressure you want. It's not based on your oil pressure, just the pressure delta across the filter. It's mainly a concern when the engine oil is cold and causes a higher pressure differential across the filter element. https://www.corvetteactioncenter.com/tech/knowledgebase/article/2012-2017-corvette-service-bulletin-17-na-157-information-on-spin-on-oil-filter-replacement-for-gas-engines-designed-with-new-oil-pump-control-systems-1363.html "Beginning in 2012, oil pumps began to regulate main gallery feedback instead of pump output pressure, which means that the oil pump 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. To meet these new engine operating requirements, the oil filter specifications of production oil filters and service oil filters have been improved. If a replacement oil filter with an internal bypass valve opening pressure specification of 15 PSI (100 kPa) or less is used, debris could circulate in the engine and cause damage to bearings and other tight tolerances areas, and eventually lead to premature engine failure." When the 2014 trucks came out most auto parts stores were listing a lot of oil filters with the low bypass pressure as being compatible. Even just a year or two ago some places were still listing a Wix 57045 for my 2014.

That's because they have a fairly high curb weight and a flimsy C-channel frame. The frame flexes so much you can really feel it in corners and over rough uneven pavement.

The filters listed in a search on Napa's website shows they all have the correct bypass pressure. Should be GTG. They look just like a Wix XP filter inside.

The older Wix oil filter that served as a PF63 equivalent and was incorrectly listed for 2014+ GM trucks was the Wix 57045 and 57045XP. They only have a bypass pressure of around 12 PSI so you really don't want to use one. They work but not a great idea. Since it will be in bypass more often, especially in cold weather.

Luckily Wix usually lists bypass pressure on their website. Here's the spec for Wix XP 10255XP from their website. Stick with the 10225 or 10255XP. Some parts stores have old stock Wix filters with a part number that's listed as working on a 2014+ GM truck but has a much lower bypass pressure.

Yeah I'm really not a fan of the "E-core" style PF63E. On my 2014 I eventually started using better oil filters but only if they specified an oil bypass pressure that matched the PF63E. If I remember correctly, Wix does offer an XP oil filter with the correct bypass pressure. It only became available in the last couple of years. I will probably switch to that filter eventually. I really don't rust E-cores.

With the complexity of modern engines, I personally wouldn't push oil changes out past 5-6k miles. These engines are gas direct injection engines, and GDI engines have a tendency to generate high levels of carbon soot formation. Some of that abrasive carbon makes it past the piston rings ends up in the engine oil, where it circulates throughout the engine oil circuits, including through the AFM/DFM system's oil control solenoids and lifters. Soot can combine with other sludges formed by the breakdown of engine oil, creating formations that restrict engine oil flow and pressure. The soot can also cause excessive wear if the engine oil film isn't thick enough (sheared down oil due to age, fuel-diluted oil causing a drop in viscosity). The oil filter isn't designed to capture these fine soot particles. Additives that act as a dispersant can help with carbon suspended in engine oil, but they aren't guaranteed protection. Every oil company swears their oil is the best at it, but like every other claim they make, there is no guarantee. In a simpler engine like the old 6.0L Vortec, you would be fine letting oil changes go a little longer. But those engines don't have complicated systems using engine oil to activate and deactivate lifters, vary oil pressure based on RPM and load, etc. Unless you're changing your engine oil more than once a month, there's zero sense in trying to squeeze an extra thousand miles out of your engine oil. Buy whatever is on sale and change it more often.

Make sure you're using a Wix oil filter with the right bypass pressure setting. At least one of the filters listed as being correct for the 2014+ GM V8's had an oil bypass pressure that was too low.

I mean, if the dealer you bought the truck from is far away and there's a closer GM dealer that's closer to where you are, you can go to the closest one. You don't have to go to the dealer you bought it from. But it's up to you. If your current dealer is willing to continue trying to find the noise, there's nothing wrong with sticking with them.
