man get some nistune with the wideband support, the thing 'should' almost tune itself.
Emance is a joke he has basically stolen other peoples hard work to get himself cash..if its a purchase he will respond(well, new purchase) but nothing warranty or return..
for a brief time he tried ,real hard. As a person who tunes my own its a pita doing other peoples cars tunes. SO many small things can completely throw it off, and getting some people to find those issues is a lot of work.
for the record mod'd stock injectors are a huge d!ck pain to tune.. current project.
