HP Tuners for 07's LS/LT models....
i still don't believe it, i wanna see dyno sheets showing improvement, and i think we need to know what he did and how he did... because i asked a local shop about tuning with teh equinox code, and he said it can't be done that he already tried....
i agree with this post. im guna need some numbers. it has been imposible for so long imvery hesitant before i go and say some thing like this works. i say we need a dyno showing significant improvement. (no offense)
