how to make my 09 3.6 SIDI commodore faster

But seriously, not much that is legal on Ps. If you wanted a rocket ship, you should have gone for a 2l turbo.
Enjoy the car for what it is, make it personal to you if you want with wheels, paint, sound system.
But nothing is going to make it a V8, so save your money, and demerit points until you are off Ps and can do the mods you want.

we all know you can spend a lot of money on a v6 for little gains and if he look in the v6 section he would find all the information

The only thing you can put on to gain lots of power is a Supercharger though he's a P-Plater as he's 18...
