The problem with the tune that comes with the maggie is that it doesn't account for other modifications. Add a cai, LT's etc and the tune will be off. With the maggie tune you'll probably be around 460-470rwhp. With a custom tune it should bring it up around 500+rwhp.
Hmmm..I was just going to tell you that you didn't need the 160 thermostat, but that's a personal choice. These engines seem to work better and make more power when warmed up.
For CAI I would look at ADM's or maybe rotofab.
Not to keen on the 22's, but like someone said that's a personal choice. I don't like the look and it will slow you down and make the ride harsher.
Yes, you can turn off AFM and torque management with a custom tune. I would recommend talking to Ted at Jannetty Racing in CT. Even though you are in Texas he has no problem talking to people and making recommendations and giving advice.
Just for you to see about where you should end up, here's the thread on my car :
