At this time you should be able to re-run the above tests with no IDM codes generated. I do keep boost below 30psi, and EGTs under 1100 when on an 6-7% grade. Towed in the Rockies and Smokey Mtns getting 10-12 mpg this way no problem. Running 23ME on CatCHER level 3, everything else set to default. I’ve had great luck towing with this tuner.
