Get a upd and knock the screen out of the mass air. Very noticable. My 6.0 ran a 16.1 @ 86.4 with only those mods. AKZ71 my exhaust is the same.

Cool, thanks for the update. Seems to me it is going to be fairly easy to mod the exhaust with it running dual all the way to rear axle like that.

Thanks,
