Finally got the chance to kinda burn down these tires some more.

I wasnt getting into more than 8 or so psi of boost as I cant figure out if it's an exhaust leak or light pinging, my new fuel set up should be here shortly. But I can say this, the Kumho's start getting sticky after about 500 feet of burn out's!
