scubieroo, before u start getting flamed on, and i noticed u did this a couple of time already but us the search button. cobb tuning accessport has been discussed many times and u will get vasts amount of information just by the search option. u will even get to compare other engine management systems.

 

not saying u cant get answersa here, but just know your most common answers have been answered over and over so just search for it.

 

It can void your warranty if your dealership finds out. FWIW, they probably won't unless you tell them. And its a VERY worthwhile upgrade from stock.
