I just looked up the SCT tuner online quickly... So am I understanding correctly that for less than $400 someone could get the tuner and increase their torqu over 100 Ft lbs to over 500 ft/lbs? Is it that simple? I am lurking and asking questions in preparation for my next truck purchase. I like the sound of the 5.0 but if what I am reading above is correct it is hard to over look
