I have an ECU out of a 2000 6 speed manual B5 S4 (A Box). APR Stage I Chip for 91 Octane with downpipe program (gets rid of cel associated with dp's), and an additional race gas file (100 octane). ECU has cruise control stalk switching between the two programs (check out APR's website for details). Chipped by 2Bennett in Davis. Looking to get $450 shipped. This is a very friendly tune, I never got any cels or had any problems with it. Great upgrade!
