nitro is a cheap option instead of turbo or supercharger.
depends on how much power and how much money you want to spend i guess.
Despite tweecers being known to work with Ford's EEC ECUs, their aussie coverage is patchy, and I don't know if the I6 ECUs have and bin files that have been cracked for tweecer usage.
It's more of a 5.0 thing.
"Rollin" began to mess around with a tweecer in his previous falcon a few years back (he's found at boostedfalcon.net), although he used a Mustang A9L ECU (tweecer compatible) and a MAF and somehow got all that working with his six.
There is no "best way" for power increase, you have to decide what you want. If you opt for a turbo kit, don't bother buying headers because you'll have to pull them off again.
I'm assuming your EF Falcon is a bog-stock 4.0 auto. The best bang-for-buck performance increase (apart from a cheap nitrous kit) would be either a manual conversion or shorter diff gears, although neither of those mods will increase your engine's power output.
