Hey guys haven't posted in awhile but I have a problem that's been bugging at me. I am debating whether or not to go ahead and invest in a handheld tuner for my mustang, specifically the SCT tuner on americanmuscle for an 03 Mustang GT... Anybody with experience have any advice/pointers/things I should know/things I can do?
