Re: need some help picking fuel injectors
24#hr will work fine or even going up to 27-30 you will be ok. you will need to tune for it though. You can use the 24s at 3 bar and increase the fuel pressure but the best way to get the best air fuel ratio is datalog and tune. if you need any assistance or pointers send me a pm.
