i had mined maped for 1.3 bar on stock injectors and no fpr and it went fine so i reakon you be perfectly fine just to bang a walbro in there and run 0.8. i will say tho i ran a blitz ecu at 1bar before i got the emu and even after winding up the boost to 1.3bar i noticed i was actualy using less petrol despite running a hell of alot more power. at the end of the day theres no set answer you could try run 0.8 bar and the engine decide to shit itself or you could do a driver and keep all the fuel system stock bang on a blue and map it to 1.6 bar and have no issues. modding your car is pu
