992HP on an almost stock 6.0L!

Colorado with a hood exit turbo exhaust? Ok, you have our attention! The first clean pass was 714HP on 14psi! So next thing to do is turn it up, and that’s what he did! The front ends starts to lift when he turns it up to 20ps and the car slides off the dyno but it still reads 909HP! Next pull he adds 20% more fuel to get things going! It ended up making 992WHP It only has a turbo cam and spring on a 6.0L but he did break some things!
