Blitz Dual Stage Boost Controller Issue?

[extraction]

Today when giving my car a bit of gas the alarm for the boost controller in the cabin went off. I have recently bought the car and dont really know to much about this boost controller but havent had any issues until know.

I am pretty sure that it is an overboost alarm which is set to 1.4 bar. When the alarm did go off I checked my boost gauge and it only read 1.2 bar. Any idea what would cause this It did not happen in all gears when going flat out and when I heard it I backed of the gas right away.

I drove my car again a bit later and but my foot down in 4th and watched the boost gauge it hit 1.2 bar again and the alarm went off.... The only thing I have done to the car is a but new fuel in the car this morning and 2 I have installed a heat shield for the pods. Not sure if I could have damaged a cable on the air flow sensors or anything else that would cause this.

Any help would be appreciated

May have had a slight boost spike which isnt uncommon.

Just keep monitoring it and see if it happens again. If it does try and replicate it and see if the boost spikes then returns to 1.2
