The quality of this tuner is great BUT UNLESS YOU ARE WILLING TO SEARCH OUT HOW TO PROPERLY INSTALL THE CUSTOM TUNE YOUR OUT OF LUCK .... THE INFORMATIONS SUCK BIG TIME expect to search out on the web, YouTube and other places that will help with the download and tuning unless you don't mind using the preloaded tunes
