Yeah, he needs to get the AP with the little jumper to go under the dash when flashing maps (reflash, not on the fly). Congrats on the new parts. As a rule of thumb, I would recommend following the traditional mod path on these cars. Look at Cobb's website and look at what mods are supported for each stage. As of right now, none of these parts pushes you past stage 1 (stock, tuned). A downpipe is needed for stage 2 to see some additional gains. I assume, as most of us, that you are running with a finite amount of money for modifications, and that will help you get the most bang for the buck.
