ideally the fuel pressure should be set by some1 tuning the car, you would be safer, having it setup sumwer with a wideband,

edit,

3.1 bar for one bar of boost safely, but i think thats ct9, with standard injectors, with your injector being non standard, you really need to get it set with a wideband, and ideally some sort of fuel controller

With 3 Bar fuel pressure and 370cc injectors i think you could well be overfuelling, symptoms sound like that too. Any way of measuring AFRs?

bacareful running too rich can cause serious problems.....bore wash....and in bad cases, u can spin a bearing if fuel gets into the oil sump via the cylinders/pistons/rings gaps
that is the last thing u would want happen

your car is most definitely running pig rich with 370cc injectors and 3 bar fuel pressure

why dont u try the stock injectors and 3 bar pressure TILL u get to the tuning place....just take it easy and stay off boost........
