Yes you can make power spraying the top of the pistons in them but it isn't going to be near as efficient or safe long term by any means. To make that duration work you would need a spray pattern and piston bowl design to allow 80* of rotation where you are still getting fuel in the piston bowl. Like he posted earlier Cummins love 30* of timing but that is mostly due to you only will hit inside the piston bowl for 55* engine rotation from injector spray pattern which as rpm climbs you obviously close that window of opportunity very fast. Towing that trailer you’ll want to watch your exhaust temps. Make sure you add an EGT probe and get the EGR block off plate that is will fit the probe you get. If all you’re looking for is a single tune go with a tow tune or a stock tune. At this time, we can only offer On-Bench DPF OFF and Tuning for this vehicle. I have a SCT GTX tuner which I like but it is a tad big.

The difference between gas and diesel pistons is diesels have the piston bowl that if you don't get it in the bowl during the injection event you will be spraying the top of the piston and cylinder walls and melt a piston down or on 6.4s crack it which is already common on these trucks due to the piston bowl design.
