Hit up Mission Performance. My car has been running strong for over a year on stage 2! You'll have to change the plugs, and get DP's for stage 2. Or just upgrade to the JB4 with the BCM so you can run map 2, also a very strong option but you'll have to remove the passenger side intercooler to hook up the BCM harnesses.
