The only chips that are worth the money are the ones that are made for YOUR CAR. You go in and the tune your car on a dyno and write the chip that way.
Chiptorque do this. I have delt with them a lot and can't recommend them enough.
a chips improvement largely depends on what mods you've already done to your car.
if you've gone nuts and done headwork, cam, extractors, intake etc etc then a cam would deffinately make the car run better (idle, performance)

Doug (SPHELL) recently had a unichip installed in his EA with Wade cam, extractors, exhaust and SVO head. It resulted in 143.3 rwkW. I think he said that without the unichip it was about 10 rwkW less. However the chip was needed because it was running too rich and not starting well.
I really wouldn't bother with the chip unless you've done lots of engine work like Doug has.
yeah i got about 10Kw's from the Unichip. Pretty pricy tho. Normally I wouldn't bother with one but but I needed it to stop the car overfuelling. The extra kw's was a bonus.
I was thinking of getting one also. I heard not to trust in the "off the shelf, one size fits all" chips as they are a waste of money.
People tell me to look into brands like, Unichip, Chiptorque of for the 5ltrs, Tweecer. As they are fully programmed to your ecu to suit your ecu.
For myself, I plan to go the tweecer way as the program re-burns new parameters to the ecu. Plus, this can be done on a home PC or laptop. It hasnt got as many parameters as say the Unichip but is extremely versatile and just as effective for use on the street and strip. The tweecer also has switchable settings from economy mode to agressive race modes and they can be switched over at anytime with a dial, (I think) so that if you want the car back to original settings you can. Made mods? chuck it back on the laptop and re-program it. No restrictions to go back to the chip dealer to get him to re-program!
With the 6's you pretty much have the choice of Unichip and other brands but your restricted to going back to the place who installed it for ya. But I have heard recently, that the tweecer will soon be available to EEC ecu's for the 6's soon.
If anyone knows of any updates to the info I have mentioned, please correct me.
