Re:Air filter
hmmm if the A/F meters are crap...then why the ---- are they being build ?, and why does everyone recommend a a/f ratio meter ?
I was planning to do the fuelmapping with the help of some dyno runs.
But another question, if i use a wideband.....than i don't have to go to the dyno to know what to adjust in my fuel maps ?
And what ratio is safe for idle...and what ratio is safe for full trottle ? (without a needless thirsty car, I'm just a 19jr student in university mechanical engineering)

Re:Air filter
Narrowband o2 sensors are not a reliable source to tune a vehicle with. Just because it is being sold doesn't mean it is a good product. 
If you want to paint a pretty picture on a dyno and use their wideband that will work, but you're better off buying your own wideband kit and tuning yourself. They aren't that expensive and are a grat tool to have around. I recommend the www.zeitronix.com kit, especially if you already own a laptop.
It sounds like you need to do some more research. Some of your questions are a bit "noobish".

Re:Air filter
a/f meters aren't crap. they're just not accurate to tune with since they don't have numbers, just lights. if your car is running lean you will be able to tell a difference with a a/f meter though. i know you guys say they suck but i saw a difference in my a/f before and after tunning.

Re:Air filter
hmm I'm doing research all i can, and yes I am a nooby. It's my first non-turbo car, that I'm going to turbocharge. (within a certain buget).
Also helping my brother to restore his porsche 924 turbo engine. Im learing from that too, but is a turbo car stock. (finally putting everything together
).
I also think it's good to have good equipment for yourself (My brother and I just bought a shitload of Facom and snappon tools once and for all), but if i don't know enough about chipping itself, and changing fuelmaps, the thing is pretty useless to me.
If i knew exactly what i was doing regaring the chipping i would buy one.

Re:Air filter
yes i can see that, but im pretty ------- bad with computers etc. I can understand most of the theory but a lot of terms are used and im still finding out what those mean. (Im dutch so....)
I'm more in control technique of industrial machines etc.
Btw, im still looking for someone who can help me with chipping etc. If anyone think you can help me (and willing to to so), add me to your MSN: royhoeks@hotmail.com.
It's not that im lazy, but usefull resources are always welcome
