Super 6 (l67) mods

[Zentisca]

G'day guys
(apologies if this is the wrong thread, new here)

I'm not too great with cars (more of a bike guy).
Originally bought a ute for the purpose of transporting my bike, but I've come to fall in love with it.
The bloke I got it from did some work to it, 16psi, larger fuel pump, encased pod filter. It's had the brakes upgraded, struts, suspension done.
I've also been told by the local auto elects that the tune on it is running rich.

I don't know the numbers that its pushing out, but a mate reckons about 350hp.

I want some more throw back, push a little more torque.

Any suggestions, build specs that anyone can enlighten me on?

Cheers

16psi is a lot depending on supporting mods, you really want some sort of cooling at that level and maybe throw a cam in there as well. If indeed it is running 16psi than it will have had to have been tuned as the stock tune simply won't support that sort of boost/power level.

Also consider a diff ratio change, making better use of the power is just as good as throwing more power at it.
