Its the reason the car will be slower than the LS3...its also a weak link in longevity and performance (we suppose). The AFM lifter design is a weaker design that necessitates lower lift cams for safety. You cannot go as big with an aftermarket cam with these lifters installed. Most shops will tell you that if your serious about performance to install the AFM delete kit.
Bottom line: If your concerned about MPG and don't plan on doing very many mods, and 12.9 @ 109 is FAST to you, leave the AFM alone.
If you plan on installing mods in an effort to run below 11.50, and don't really care about giving up 2-3 MPG, remove it and don't look back.
