Premium fuel? I doubt reg fuel would do anything. I've seen a dyno with the tow tune.... Made almost 350 wtq with 285's

It's a turbocharged engine not a N/A. Plus we also have a intercooler to cool the charge air. I think this thread is way over engineered for the little gain you're going about getting. Besides everything is ecu controlled. There are many debunking dyno videos on yt proving pretty much most air...
Right. This is a complete waste of time. Nobody is going to waste their time... Especially with how the world is now and the epa standards. If it hasn't happened by now it won't.
Where tf are you going? Without towing you can go 300+ miles. Ya mayswell just buy Jerry cans. Towing I don't want to be using Jerry's all the time on the long stretches. When you bet 5 mpg a 19 gallon tank is kinda worthless.
