Hey There,

Long time no seen... Last time I asked for a help in here I get 100% right response

Having a trouble with boost up for my Caldina ST246.

I have a front mount cooler, 3 Inch Downpipe, BOV, Controller which is mechanical and all of those parts are from the aftermarket...

The problem appears when I reach 0.9 Bars and than it gives me fuel cut.

Does anyone know how to handle it without any big troubles or getting the new standalone/piggyback ECU? ))

P.S I tried to mount Zener Diode to the map sensor it didnt work.
I cancelled the wastegate hose which leads to VSV and it didnt work as well.

Thx everyone in advance
