I am a student at Auburn University in Auburn, AL rgiht now, which is the HQ for APR. I have their software upgrade which gives about 52 more HP and about 100 Ft-Lb more tourqe. THey are also an official dealer for the carbino cold air induction unit which i am about to get. I am also thinking about getting the full exhaust that APR offers. If you get the software, cold air unit, and exhaust from APR, which they call a Stage III package, you can expect close to 300 hp and about 40% to 50% more engine efficiency. I think the carbino cold air intake is a good deal, because it maintains the most factory elements of any other cold air unit, which helps with warrenty issues. It will also give you a really good sound out of the turbo. I will let y'all know how the install goes and everything.
