If you want to chase the dyno all day that's cool, but last time I checked what's important is how you do at the track and how fun it is to drive, not about some number from a dyno
(but you'll see those too when you check). We have taken care of the A/F ratio and your knock sensors still work. I'd just do it. You can tell from what Chris is saying, we're here to back you up. If you're worried don't be, the tunes will make your car GO!
