Hi I need a little advise.
I was gearing up to run big power on my Subaru classic but car has been off road to long and need space at work so putting it back on road with standard power. Problem is i have already swapped the fuel pump for a 340 LPH hrc pump!! Will this be to much for the standard fuel pressure regulator or will it cope??
Thanks for any help
Pete

 

Hi Pete

If you are swapping for bigger pump without the mapping,get at least check for AFR or if you have wideband try monitor AFR on idle,load etc

Cheers for help, do you think the pump will be to much for the standard fpr then?
Thought as long as fpr same then pressure to injectors will be same?
Cheers
Pete

 

I wouldn't worry about the FPR.

 

fpr will be fine.

 

Thanks for all help/advise.
