I had mine for sale a few months ago but I had the front o2 sensor crap out on mine . After buying a new one , it took some time to get everything tuned in again . It was throwing some weird codes for some time . I didn't feel comfortable selling it to anyone , so I decided to keep it . I had Zippers mess with the map a little at Thunder in the Valley , and now it runs really good . So I guess after all the messing , I like it .
