[QUOTE="02bigstrokin, post: 1209843, member: 12110"] So I decided I would tow one of my friends rock crawlers up to the trails for him today. Put the sct in tow tune and it pulls pretty good with the street max but when I hit a hill climb and it gets in a hard pull I'm getting a loud screeching/ howling sound that sounds like a old 7.3 turbo flutter. its done it three times now on the way up here? Anyone got any ideas? I don't have any smaller of a tune to load up. Boost was at 34 one time, 22 another time, not sure on the third. All three times today have been in 5th gear. It did it to me one other time in 6th without a trailer going up a hill in the race tune at like 65mph. Thanks [/QUOTE]
