Hi guys
I've read somewhere a while back that you can increase the pressure by denting your stock regulator, this causes more tension on the spring inside increasing fuel pressure.
Can anyone confirm this ?

Yes, the fuel pressure regulator can be squeezed in a vice to increase the fuel pressure.
But, why do you want to do this ?
You'll only gain higher fuel consumption and a loss of power from running too rich unless you have extensive engine mods (lumpy cams/big valves/increased capacity/etc etc). If this is the case then you're much better shelling out for a remap, at least it'll run properly.

Seconded, more fuel is needless without more air.
