Just happened to a buddy's 2012...Started acting funny on the way to work, sat for 8 hours, had no rail pressure when he tried to fire it...Dealer is replacing pump, injectors and lines under warranty...30,000 miles, completely stock...
What is serious TQ to you?...Most of these modded trucks have over 1,000 and have heavy 33"+ tires...A lot of us went with Cal-Tracs for their adjustability and cost...
