Yea, they really ”dumped on” it by going to a more powerful, more efficient, and lighter engineGEN 1 hands down. It's the truck that started it all. Everyone is chasing the standard that FORD set (then dumped on by getting rid of 6.2 engine). GEN 1, supercharge it and have fun.
Gen 2 exceeds every standard that the Gen 1 set, period.
