Hi fella's,have been having starting and idling issues with my XG-ute, so have decided to upgrade my injectors with 20 lb au injectors,question is I have a 300 kpa xr6 regulator here but will it make any difference without a fuel pump upgrade as the engine is stock besides pacemakers-2 & a half " sports exhaust with a large pod filter and thermo fans,any input much appreciated,ta in advance,John.

On a stock engine, the 300kPa reg won't do anything. Have you installed the AU injectors already? I found the engine ran slightly smoother with them (but then the original injectors I had could have been partially blocked...
 ). Have the spark plugs, fuel filter and fuel pump ever been replaced?

Hi,yea replaced plugs fuel filter,just got the injectors in this evening-made big difference in mine but the old injectors and ports were full of dirt and carbon,id say thats why they've made a big difference,better throttle response too,I havnt changed the fuel pump thou-do think I should and if so standard or should I go with a bigger pump?
