Ok now i had a bit of a thought about it:
I am worried about the ECU shitting itself with these new cams, they normally come with their own chip, but it isn't programmable so i didn't buy it.
Now, i am not too worried about ECU stuffing up with A/F ratios etc, that can be fixed otherwise, but i am worried about timing issues.
There are two general solutions for it:
Option1: Chip:
If i'd get one i want an adjustable/reporgrammable one. SO i looked at chiptorques, but i got intel that they tend to have problems with them ... so i am a little touchy when ppl who work for that company and tell me they have probs with their product. Are there any alternatives for that? BTW don't come with powerchip .. bad rep!
A must is: it must be reprogrammable for future mods!
Option2: Piggy back ECU:
I got suggested a Link unit to use piggy back, but the things i dont like with that: 950 bucks without gst and it is not adjustable. The adjustable units are even more expensive.
So my Q is: what is a cost effective solution for my ECU? I am looking at 600 - 700 max and it has to be adjustable!
BTW i gotta keep the original ECU for transmission controle and other things.
For those who dont know my car it's an AU falcon and i am using a tickford ECU unit.
I mentioned the A/F issue before and i was thinking of throwing an adjustable fuel pressure regulator for constant pressure onto the car. The one i had a look at was the malpassi AFR and would fit straight on. Is it worth it? and other options and how much?
Cheers

Who told you they had trouble with a ChipTorque chip on Au Falcons?
Not being defensive, just don't know of any problems with AU falcons. Let me know if there is, though.

i hear from someone who worked/used to work for chiptorqye that the reporgrammable ones tend to fail ...

i thought all chiptorque chips were re-programmable?
about powerchip i completely understand, the head honcho over their made a shambles of an interview with autospeed, lost a shit lost of customers with that 
Well i have a chiptorque chip install on my mx6 turbo and for the most part its been pretty good, as far as i can tell. When i drove out the idle was just as smooth and well acceleration was even smoother, best thing of all it lifted the factory fuel cut at 11.99999' psi boost which was the main reason behind getting the chip in the first place. Now from what i understand chiptorque manipulate fuel and ignition curves on a trial basis, constantly changing values within the ecu to achieve the desired (or a more appropriate) air/fuel mixture and ignition timing. The procedure does sound a little iffy, i understand that the system has no where the amount of resolution as a complete aftermarket ecu but thats understandble, basically its meant for cars with a limited amount of modz, there is only so much thats in scope of the factory ecu's capabilities.
for your purpose evil im not so sure, changing the cams will require quite a bit of tuning with a chiptorque chip i beilieve but on the other hand im sure its been done a million times over, probably best to have a chat to their marketing department 
as far as the an adjustable management system at 700 - 800 dollar i think you will be very hard pressed, the cheapest option would be a chiptorque chip, but that will set you back closer to a grand after all the tunning. An interceptor device might be the way to go in the form of a UNICHIP, i believe they can be had for around 900 bucks + tunning, or alternatively you can go for a complete aftermarket ecu like the stinger which i think goes for about the same price (900) or so but then of course you will either have to install the thing urself or pay for someone else to do it...
i know rodhog has a unichip, he might be able to answer a few questions

Why I love carbys easy to change cams and get it runing right
but, let me note a few things first your Factory ECU will not shit it self more Just get confused, rich or lean stage 3 cams are still quite mild but also quite rough.
The best option in my opinon is to piggyback a fuel only ECU but I think on the Fords the ECU does alot of work so a Unichip maybe be a better option.
Unichips don't loose ther memory or the ECU relearns it.
all that stuff you mgiht have heard aobut ECU's learning how to avoid interceptors is wrong, it did happen but one early model cars but everything has to be tried and tested first.
Unichip would work just the same as the chip, the advantage the unichip has is being able make adjustments at a latter time with easy on a dyno ( but you do have to use and aurthorsized dealer)
Again you are limited to the factory ECU but then again new factory ECU's are so well done there almost spot on except for saftey measures.
I would say talk to a tuner to see which suits your plans.
