4 bar map sensor question before mapping
Hi people in need of some advise, my car is due in with duncan on 5th april.
I was doing finishing touchs to have it ready, i fitted the perrin 4 bar map sensor and the car ran like crap, is this down to the map sensor, i have fitted the old one back on but havent had time to start it up since but do i just take the sensor down with me and stick it on before the mapping and is it normal to make my car run like rubbish without a map.
Its a 04 sti blob eye any advise would be great 👍

yes the 4bar map sensor unmapped will have it running like a pig. Make sure when fitting that the little rubber o-ring is well seated as I've seen a few that like to leak a little and give a duff reading.
Hopefully there's a nice set of rails to go with the braided lines and the FPR?
