Message	I'd make sure the 555cc injectors aren't flowing at 615cc by checking the K-Value on the Eprom. I assume it's going to be 210 (per TunerPro). I have some 555cc injectors that ended up flowing at 615cc and had to adjust to be 195 for the K-value before the black soot disappeared from the tail pipes.
