Defi gauge inaccurate
Hey ppl, just had my car retuned and the tuner said it is set to 1.3bar although my defi bf boost gauge is showing 1.5bar. The original tune (by a different workshop) was set to 1.2bar and this is what the boost gauge showed.
I'm trying not to doubt the tuner but I thought these expensive gauges where meant to be highly accurate. Anyone else's read off? Scared it might be actually 1.5bar which isn't safe so I'm told using the Perth-WRX mobile app |

Do you know anyone else with a gauge to test it? Did you do the re-calibration yet?

buy a $15 obd bluetooth scanner and get the app for your phone (torque if you have an android)
monitor the boost as per the ecu |

Where did you buy your Defi from?
Which vacuum line is it connected to?

Wont work for this application. Stock MAP sensor is only good to about 18pound. (Least thats where it maxes out on my forester.) Even if actual pressure is higher than that, it will still only show that.

Look at my track vids. Boost hits a wall at 18psi. But in reality its up to about 22psi. Thats recorded from the ECUs MAP sensor via Tactrix Openport 2.

Pretty sure you can buy 3bar MAP sensors (2 bar above atmospheric, and 1 bar below). Just need the pressure to voltage rescaled in the tune. But its not really worth it unless your going for speed density etc.
