That's rightNice bling, but the restriction in these motors is in the head, nowhere before.![]()
Wondering if you had a now longish term update on the add a pack? Still sitting at the .5-1” lift from it? And still noticeable improvement the over the giant overload leaf? Is the squeak or noice any worse or better?

Have to hand calculate it. My 2019 SO would show the same and I was actually getting ~`15mpg. My 2022 H shows almost half that. I plan to do similar mods, and would love to actually get that kind of mpg gains. Makes me want to install my 5th gen intake horn and exhaust I have sitting on the shelf sooner rather than later. Who's doing your engine management?If this is accurate, this is almost comical for a truck on 37's. A mix of the intake horn/grid heater and changed engine management. It continued to go up to 21mpg on a 200+ mile trip.

Two things…
1. What is the purpose of the grid heater delete? I was going to get the monster elbow and just leave the delete cause I live in Florida but why do that considering it seems like a necessary function for cold weather?
2. Did you do the whole package delete with all the Americas Hat parts? DPF, CAT, DOC, DEF, EGR, SCR?
If so that 20mil could be accurate or more?

Considering the design has never changed... not sure how.That bolt issue was almost 10 years ago, they gotta have it under control by now..
Thats still a huge improvement from where I am currently at. Honestly any improvement will be appreciated. Can't wait to get some more of these mods done.So hand-calculated it is 17mpg on a tank with a good mix of highway and city. It is unfortunately skewed. Not too sure why it is now when it was accurate before.
