Hey guys. I have an '06 PSD with 30k. I have the SCT Livewire, afe airbox, and turbo back 4" exhaust. Before I have problems Im getting a friend of mine to do the the head studs. He's a ford mechanic and is doing it on the side for $900. I thought that was a pretty good deal so Im doing it. My question is after I do this, is there anything else I need to worry about if I run my SCT on the "performance" map??
