Well here is my story, i went with the 9K LB toyhauler to the mountains this weekend, on the way up i had to pull a 6% grade it was 110*and i had AC blowing full the temp gauge started to the top so i backed out of the throttle and it came back down. On the way home it was 104* and 20-30 MPH headwinds, i got pissed becasue i was being passed by everybody and there mother so about 35 miles from home i couldnt take it anymore and i hammered it down. The MPH came up from 60 MPH to 73 MPH and i was rolling with everybody, i was watching the temp because of the previous event, the temp was good, but the boost gauge which has always maxed at about 27PSI to 29PSI was hitting a solid 31PSI then dropping to 25PSI, about 25 miles from home there was a loud noise like the tranny shifted really hard and the truck slowed way down and i had an ICON i had never seen before, looks like a wrench. All the gauges read good but boost was topping under full throttle at 19PSI, since the gauges read good i kept going to home now at 45 MPH. At home i turned it off and restarted it ICON is gone and truck runs fine. DID MY TRUCK PROTECT ITSELF FROM ME????????
