I would go with skunk2 gears cause AEM's have a tendency to slip. also for added safety get the inline pro head gasket and block gaurd. www.inlinepro.com

also I would recommend a rev hard kit over drag. they are just better all round kits.

I run 15psi daily with the head gasket and block gaurd from inline pro. I have DSM injectors and vafc with a 12:1 FMU and missing link. the system works fine but expect MPG to suffer....good luck
