50MPH+ up a 7 - 10% grade with 4000 gallons... Guess the ol' ISX isn't all bad.
@PenguinLTZ can you do some data logging for me? I need to know your idle and WOT readings for the MAF... I might have found my culprit, lol
Please and thank you![]()

Have you cleaned it? Hopefully it ain't a K&N filter in that airbox
39g idle 412g WOT
I kept everything. I have the stock tune, ready to put back in. Honestly, if I went to sell mine 100K from now, I would feel better about the truck, not having EGR flowing into the cylinders for 100K, and my tune is mild. I don't roll coal, I can't! It gets a mild puff of black if I am at the low end, and mash it enough for a 1 second lag. I can tap the brake and spool it instantly to avoid smoke altogether. Yeah, the coal rolling guys are making all of this way too noticeable.
As for the legality, you are absolutely correct. We had to check all 07 and newer trucks before reselling them, to ensure federally mandated emissions were in place. Pickups would be no different

That is what I thought. I would guess that if you traded and they didn't check you got lucky.
I know a few have taken all the emissions off their Cruze diesel and didn't keep anything. Not sure if that was a wise move. On a side note they are claiming 60+mpg now and better performance. Which is a given if you ask me. I might take mine off once the warranty runs out.
