So did putting the original program back in restore the power back to what it was?

Looking back at records, I think the fuel consumption started before everything else. The mileage is down 1- 1 1/2 miles to the gallon. With a little less power. Seems like I have to put my foot in it more.

The original program did make a noticeable difference. It seems to run and pull much better( doesn't fall flat on its face). It's acting like a leak but I haven't found anything significant. Like I said I'm going to order a plug kit designed for a cac system. It was falling flat on its face at 60 mph empty.

Also there was a guy on social media asking if he needed to calibrate his ecm because he installed a new egr cooler. I'm sure whoever sold it to him told him he was supposed to. I commented don't do it, mine hasn't ran right since. Another guy told me to bring it back he had the same problem. I don't know what they did, but the dealer told him internet dropped while calibrating his the first time.
