You'll get different people telling you different thing about what AFR to run...IMO, 13:1 is the best mix of performance as well as longevity...

As for "blowing up the car" with the FIC...my answer would be that it's really not very likely. Keep in mind that you still have your stock ECU in place with all of it's safegaurds...if you leaned it out too far, you'd start to get knock, the ecu would see that and pull timing to keep it from hurting anything. But honestly, you'd have to lean it out quite a way to see any of that activity...

It's actually kind of hard to blow up a stock motor these days with all the safety stuff in the ECU. You have to be boosting or using nitrous improperly or doing some other internal non-stock modifications...using simple bolt one and doing some fuel tuning with the fic shouldn't cause you any major issues.
