...you might also be able to find a few of APR's beta K04 programs floating around on an A-box ECU (and you get to run on 93 octane gas). They won't sell it or let you have it anymore, but I've been running mine for a year and a half now without any issues, and I'm several car lengths faster in short races than APR or MTM Stage II+ (chip/exhaust/downpipes) S4's.
