Hi I have a 58 plate st2 facelift and it appears to keep going into limp mode I have an dreamscience stratagem race edition handset to alter the maps if a select a map the car runs lovely and you can see it's working as it should full boost etc etc then after a while it cuts the boost back to 0.4 bar and the car still runs ok with no warning lights but just at reduced boost and power , I can turn the car off and on again and it's clears the fault for awhile longer but then it comes back , I can also plug in handset and re-install the map and as above all is fine then it slips back to only 0.4 bar can anyone help me on this , ps new St owner so be gentle with me on this lol , thanks in advance
