Fuel cut? Boost overpressure? Hdi

[Theclangray]

Hi all.

I have a 12 PLT 2.0 hdi with stage 1 Celtic tune.

On 4 occasions now I have felt what I think is fuel cut, each time acceleration hard up a slip road...once it threw a code for boost overpressure.

I've been told the Celtic tune is demanding 1.7 bar,

What is the fuel cut pressure on these motors?

Could this just be an o
ld boost controller allowing a spike or am I too close to the cut with the stg 1 map.


Any experience much appreciated.

Apparently it throws up a P1112 code ? Diesel high pressure monitoring- Pump fault ? Mate of mine found this he was having the same trouble

Ah..slightly different...I'm not cutting out. I get that single bump of fuel cut, then car drives normally. Car is pulling and driving well other than the OP
