we installed the ms2 extra, downloaded the tunerstudio ts and an msq from simtech, and proceded to start the car. ran phenomonaly up until a short drive which started great until the motor started running lean with an AFR reading of 18. After barely making it home, we pulled out the spark plugs which were charcoal black and dry. AFPR read out at 43.5 psi, vaccum gauge reads 10, any suggestionswould be highly appreciated.
