is the v8 map sensor the same as the na 6 map sensor? if thats the case the turbo one needs a different plug and you just wire it back to front. so say the na map sensor is 1234 wires you just go 4321. guy who sells the knock box sells the plug and play looms which are about $30 otherwise the correct plug for the ba turbo map sensor is about $30 also.
ba turbo reads upto about 26psi also
