Hi all I'm looking at buying a second hand chip torque chip for my ef fairmont it was in a ef falcon and have been told it's plug and play I am looking at paying 60 for was just chasing some more info in regards to if it needs to be retuned and so forth any info would be great

The chips are programmed to the car.

On the chip itself there will be a code, if you call chiptorque and quote this number they can tell you the specs of the tune it was designed for.

I have a chip on my car that is for a cam, extractors and a sports exhaust.

Google chiptorque for the website and find the contacts page, there is a phone number there and the receptionist is very helpful.
