STAGE 1 upgrade

I’m new to this forum and also just recenlty purchased my 2012 Stryker. Love it! but dissapointed in it’s low-end performance. I’ve done some research and I’m I’m planning on doning what my mechanic calls a “Stage 1 Upgrade” – putting on the Van & Hines Twin Slash Staggered pipes, Intake air filter, and Power Commander, and dialing it all in on the dynamometer. Cost is going to be about $2k which I’m fine with, just want to make sure I’m going to see a performance difference when it’s done. I’m looking for feedback from anyone who has done these upgrades, and is an “Auto Tune” nececary also or is that already part of the Dyno Jet Power Commander that I’m getting? Regards, Terry
