I'm just in the middle of a turbo change & stage 3 so I've just changed the turbo, intercooler & map sensor (3 bar) and run the car up to temp to check for water leaks. I haven't fitted the injectors yet so the car is on the NMS gunship map at the moment.

I have an erratic idle so I wondered if the different MAP sensor could be sending it confusing signals? Obviously I will not be driving the car until the injectors & chip are changed

Thanks
