Re: 3.0 gtv performance chip
Hello and welcome.
You really need to take some time to search through some threads - you'll find loads of them on the subject and some very varied opinions.
Have to ask though: exactly what sort of performance chip are you referring to? The term "performance chip" usually (but not always) means the resistor you connect to the AFM or MAF. If that's the case, I'm saying no more on the matter than chuck it in the bin.
Carbon intakes. Hmmm. Expensive and mostly cosmetic.
