It's recommended you use a 3 bar map sensor as its suppose to me more accurate than the stock sensor.
Same as connecting up a boost gauge.
Spot on bud... its not essential to install for 1.2bar.. but its much more accurate than the oem sensor so its always best to have
kon
I would be more worried about over boosting if Ur map sensor is maxed and it's tuned for 1.2 if u get a spike to say 1.5 it's bye bye black bird
but that could happen with a 3 bar map sensor???
Yup that's the one bud lots of tuners don't do this thoyes, i was just stating that a 3 bar map sensor on its own isnt any safer.
i know what your saying though mate. allows you to tune perfectly up to the point the customer wants the boost to be at and then you can be safe after that point.
