so I'm guessing livernois, whipple, roush, procharger, hennessey(yeah they're crap, but if you do the tune and install yourself, you'll be better off, and they do use good parts most of the time), volant, 5 star, kooks, AFE, stainless works, Airaid, K&N, diablosport, SCT, superchips, and all the other vendors don't make any performance upgrades for the 6.2L, look around, there are a ton of performance mods for the 6.2L, no, we don't get all the small name companies building stuff for the 6.2L, because we spent 50k+ on a truck, are you gonna get some cheap mod that will more likely damage the truck than improve performance? The small name companies have to build stuff for engines with 100k+ production numbers to be able to make any profit. The 6.2L engine has every mod covered, we just have a few very high quality products, instead of a crapton of low quality products you have to sift through to find anything worth even spending money on, to get the same quality product for a 5.0L, you'll be spending the same amount of money, and remember, the 6.2L is at the very base of what it could be, it has 2 valve heads, low tech head design, bare bones exhaust manifolds, single overhead cams with emission focused variable valve actuation, the throttle is limited to 20% until you get over 3,500 rpm, it has capability for direct injection, but they're not in there yet, a non-performance oriented intake manifold, it has amazing potential, whereas the 5.0L is halfway to as far as it can go from the factory, and it makes the same amount of power
