I have just fitted a new bias system to my rr had a problem a while back of lumpy on idle got that sorted to much gas pressure so now all was ok for a day or two now the car is cutting out or stalling when the car Is put in park only sometimes has anyone come across this before.

It's set up wrong. Re-do your calibration when you tweak the gas pressure. Check the injector type/nozzle size. Did you tweak both halves, assuming you have the siamese unit?

When i tweak the gas I do a recal every time my injectors are biagiotti fast not sure if that is the right spelling there are black injectors this is what I have picked in the solfware . By tweaking both haves do u mean bank 1 and 2 the kit is a Tinley tec bigas sgis-n

do you have the double reducer fitted to the vehicle? If you do, have you tee'd both outputs together.

the gas pressure should be around 1.1/1.2

Done a number of theses engines with the bigas system and never had a problem
