Okay, first up. Replace your cat. I've explained it to dozens of members, the fine handed down by the EPA (and it's an Australian wide thing) is up to $10,000 for a faulty catalytic converter. It takes the police less than 20 seconds to test it on the side of the road. I know more than one person who has been hit with it, and they often have to sell their cars to pay the fine.
Onto the real stuff now:
Make a custom box (just out of sheet metal) for the pod filter and get yourself a Cold Air intake for a VS supercharged V6 and fit that...it'll help a lot.
The V8 t/b will fit, but won't give you any extra power, it will make the throttle response a little firmer but there's no extra power to be had from it. Before you upgrade to the V8 t/b, clean your current one and make sure it opens to 100% (most don't). If you have an auto, make sure the kickdown cable is well adjusted. http://www.vncommodore.com/forum/topic.asp?TOPIC_ID=394
Also...if it's an auto...a stage 1 or 2 shift kit will really help it feel a lot more lively. Cheap enough to buy, and easy enough to fit (I've been told) so long as you are fairly good with your hands.
The upgraded injectors may actually be slowing you down, if they are oversized you might be pumping too much fuel in there...if that's the case the a/f ratio could be up the creek which can result in lower power figures. Upgraded injectors are fine so long as you have the engine re-tuned for them. Otherwise they are just a waste of fuel.
The custom chip...that's a damn good idea. But believe it or not there's not a HUGE amount of power to be gained on the VN V6 (without using rediculous amounts of fuel). Having your pipes (with a WORKING cat) will help though, and a CAI will add to that again. If you really wanted to make the most out of getting a custom chip done, I'd look around and try to get a set of higher ratio roller-rockers something about 1.6:1 would be really nice. Gives you the benefits of a cam swap for a fraction of the cost. 1.6 rockers with a custom chip and you'll start to really see big improvements...however it's not a really cheap thing to do.
Whatever you do, don't get sucked into any of those dodgy e-bay scams about putting a resistor across the MAT sensor or anything like that...it's only a quick way to kill your engine.

Seems like Trizo beat me to it.
The reason that it's not good for the pod to just sit on the end of the pipe is that it sucks hot air. Hot air is less dense than cold air. Being less dense it contains less oxygen. There's three things that fire (the 'explosion' in the cylinder) needs, fuel (petrol), ignition (spark) and oxidiser (oxygen). The colder the air, the more oxygen gets in there...the more oxygen the bigger the bang...the more power you get.
The CAI (cold air intake) will set you back about $50-$60 from a Holden dealer.
The shift kit (I've seen them bouncing around on e-bay) somewhere about $50 I THINK (don't quote me on it). Check it out for yourself.
And the roller-rockers, get in touch with someone who can get Yella-Terra roller-rockers for you. And get a quote...not really a cheap upgrade, but well worth it. |

Hmmmm... $900?
When I bought my roller rockers I went through Yella Terra direct- I believe the Street Terras for a Holden V8 are around $500 - $600 so I'm guessing the Holden V6 kit isn't much off. If you've got a bit of nous, or a mate who does, you can fit them yourselves in an afternoon. Once you've done that I'd get a retune and custom chip to take full advantage of that and the oversized injectors- just remember thats about another $1K though! |

| Custom tune is about $80 (so long as you've got your own computer) and a few days of mucking around to get it right...it's not that hard to do it yourself. I'm half way through doing a how-to on it. It's all very easy so long as you understand the basics of how a 4-stroke engine works. |

| Good call- but shouldn't really be attempted by those who aren't sure. I've heard some pretty nasty horror stories... or are these unsubstantiated? |

It's possible to kill your engine if you take massive steps. But if you take baby steps (that's why it takes a few days) you can get a DAMN good tune for bugger all cost.
It's not super hard, so long as you know how to use a computer and a few of the basics of the engine. |

I'm going to go through it all myself, if you want to have a bit of a play yourself, get your hands on a copy of tuner-pro, and I can send you the ECU and memcal files so you can see it all yourself.
I don't release 'previews', I only release the finished product. It might take a few more weeks, but it's going to be a damn good one. |
