Seems needless engine mechanical complexity for what appears, from my initial research, to be minimal gains, and hoping the DFM can be disabled by some means so I won't have to experience those things I read being caused by AFM. Understand DFM is mechanically not as complex as AFM and may be a bit more robust, but I'd rather it not be an issue at all. Fuel tank size is ridiculously small considering many people will want to tow with their half-ton. Already looking at replacement options for a gasoline tank for late model GM pickups and finding nothing. Diesels have a large selection of replacement tanks, and I wonder about the possibility (and legality) of converting a diesel tank to gasoline to give extended range. The 46-gallon tank for my Tundra was the best $1200 I've ever spent, for the peace-of -mind I get from not having to plan a highway trip around a fuel stop every few hours. That 46-gallon tank of ethanol-free gas will easily get me from Seattle to Sacramento. I hope to be able to find something similar for the GM truck I want to buy. Steve

Thanks. In 156,000 miles, no troubles at all. Fresh fluids on schedule, replaced serpentine and brake pads at 95,000 and spark plugs at 120,000. What I'll miss most is the 46 gallon fuel tank I had TransferFlow install back in 2013. I don't tow, but being able to drive all day (700+ miles) on the freeway without worrying about fuel stops is great. Also, the Tundra is stiffly sprung, so I hope these new 2019 GM pickups ride a bit smoother. I'll likely get one regardless. My wife and I are recently retired and able to travel, and one of the new GM pickups is what we wish to travel in. A little concerned about this stop/start thing and the DFM. I know the stop/start can be switched off, but I hope the DFM can be as well. Steve

But if someone was to engineer and sell a dipstick retrofit kit, I'll bet many kits would be sold. This is a real opportunity for some adventurous soul. I saw one of those videos, too, and it looked like a fairly straightforward bit of engineering to fit something into that check port (where a dipstick tube could go). I am currently driving a 2010 5.7L Tundra and plan to trade it in on 2 019 Silverado or Sierra, soon as they arrive for test drive comparisons. I hate not being able to check the transmission fluid on the Tundra, and intend to attempt to devise some easy way to check the fluid on the 10-speed transmission behind the 6.2L engine while I wait for that retrofit kit. Hello to all from Bremerton, Washington. Steve
