Yes, but neither of them work with aftermarket intakes. You listed stage 1, then stage 1+, then stage 2+ in your post, the only one of those that you could use the OTS map for is the first one, both the stage 1+ and stage 2+ means a custom dyno tune by a professional (IE: several hundred dollars each). If you're going to get a custom tune, you might as well just go stage 2 and get a custom tune via open source immediately, instead of spending $600 on an AP, then $300 on a stage 1+ tune for the intake, then another $300 on a stage 2+ tune after the downpipe.
