emre. yes there is more there ... next will fit a 3.5 inch exhaust.....cant put any more timing in it.. but with 12.2 or 12.5 afrs on c 16 will make more power.....
last week we ran on a 4wd dyno and made 492 awhp in shoot out at 25 psi boost , c16 , the temps were a bit higher....so we settled on that boost limit to be safe....
keep you posted ...
