Outer Limits 4x4 Board

Gday guys, my dad's got an 02 hilux dualcab and wants to upgrade its power. He has openning the exhaust up all the way through from the turbo. And when we checkd the boost it was running 10psi from factory??

Anyone upgraded with good results, any power figures?
Thanks

my brother is getting a chip for his 3.0 turbo tomorrow. its costing about 1 grand i think, its ment to have alot more torque and power. ill let you know how it goes.

Sweet, ask him to get before and after dyno readings on the same dyno.
