It take a bit for fuel economy #s to balance out after retuning so it will be a bit before I can give any numbers there. This is a 100HP tune so I am looking to test something smaller to see if things improve over the 100.

Overall, it woke the truck up and lets it dance now.
Thanks for the update.

Regarding fuel mileage, what does your gut tell you, think you had a good increase in mileage???

That piston isn't from my truck. I've no problems with it this far.

I got 807 miles out of my last regen cycle. Kory has not started tweaking it for fuel economy yet. Hope to start that this week. Right now I avg about 17 around town, driving it like I stole it.
