First long tow and climb (vantage grade i90 out of Columbia gorge then I82 to yakima)went well. Truck was cool and no codes so pretty happy. Next pull was from Yakima up white pass to i5 and over to the Oregon coast. Also truck stayed cool and no codes. ambient was cooler than summer at about 75deg. Did get a clean exhaust filter message after dropping trailer in Yakima following the vantage and i82 up and downs. Went for a drive without trailer and soot back to zero. Good so far and happy with Johns tune. Love the insight for knowing how fuel temps and egts are. Used m5 and kept revs up. Don’t think the fan locked up once.
