Couldn't tell you. I have a 93. Visit www.jetchip.com

either should be able to give you an answer. It shouldn't really matter one way or another. Mine was a piggback, yours may not be, but the results would be the same. They're specifically tuned for your particular year/model, and Stage 2 also takes advantage of intake and exhaust mods. The chips are dyno AND track tested before release. I'm VERY pleased with the performance increase in mine, and I'm also starting to notice an increase in efficiency, also. More on that later when I confirm it.
