American muscle sells this SCT Mustang 4-Bank Eliminator Chip for 88-94 stangs. Is there such thing as over the counter budget tuning? has anyone used one of these after a few bolt on and noticed anything? I get mixed reviews on chips that come with tunes. I know dyno tunes are more expensive but they are more custom for your car. I have a couple of mods on my 92 GT, Trickflow upper & lower intake,bigger throttle body,CAI, and I was wondering which tune, if any would help my car the most? I know the chips are cheaper but should I just go all out and get it tuned on a dyno at one of the local racing shops?
