Buildeing a truck up a bit is a must.... yes, a stock truck isnt gonna build much in low range 1st gear anyway but saying a vvt needs X amount of egts is bs, a vvt will spool as long as the rpms are there... 300*...700* it dont care, its gonna try and make the boost its being told to make, we leave the line @ 1000+ degs, but its a lil differnt animal!
