CirrusWRX, you may want to add to #9 that ecutek users not remove larger injectors and replace them with stockers unless they can immediately get reflashed. what we did was take an ecu that was tuned for the STi pinks and then adjusted via DD live tuning to be scaled for the smaller stockers. this was a band-aid to get me to work (although very slowly) until it could be flashed. i was legitimately running the same AFR's as i otherwise would have, but the ecu was unhappy with something causing the code. i was also triggering MAF sensor failure codes at the same time.
