    E67 ls2 bottom end to ls3 top end

    Doing some remote tuning for a guy and he has an ls2 bottom end with a ls3 top end in a chevy Colorado. Hes using tbss throttle body and the map sensor from an ls3. He put in the linear stuff but were having problems with a map barometric pressure circuit range code and sluggish throttle response. Should he go with an ls2 style map sensor, even when we put the exact same linear settings it is still showing a difference in the comparison log. Also showing differences in the electronic tb even though the numbers are an exact match. Any help would be really appreciated thanks
