I'll ask for the exact mod list, from top of my head, he's got turbo back exhaust, intake, boost controller at 21 psi and he's tuning with one of those ecu programs that give you full control, since that run he's checked for leaks, added water/meth and tuned a little more, we are in for a re-run probably probably Sunday he's only day off will video for sure.
He should bring it to a real tuner. With those mods and water meth he should be making upwards of 360 awhp and weigh less than you, the stock evo 9 turbo is larger than the K04 as well, giving him the top end advantage..
