Has anyone used this tuner yet? If so what are your thoughts on the performance gains of it on the 91 and 93 tunes? I already have one for my 15 Sierra and it did AWESOME things for it so, figured why not give them a shot again!
please dont come here telling me to use other tuners and such. that isnt what i asked. i asked specifcally about the Diablo In-tune tuner! Thanks in advance!
