My engine is all stock save for the supercharger kit, you should be fine. The recall dealt with a horsepower issue. The exhaust was more restricted than originally planned.. I believe. The fix just frees it up so the HP number is at 320 at the flywheel. At least that's what they told me
Mine was already fixed when I bought it, the people at the shop said that was what it was. You will most likely find a fixed one by now anyway.
