Very few people bother with NA tuning these days due to the expense of it, cams and a remap would set you back £300+ easily, and the only cammed '6 I know of with cams, map, induction, exhaust and a port and polish dyno'ed at 193bhp for over a grand spent. You'd get a much bigger gain with forced induction, had a look at that?
