Re: Fuel pressure regulator

fpr does exactly what it says, you can get variable one and up the fuel pressure instead of changing the injectors, but for early car the injectors are so small its not worth it.

Re: Fuel pressure regulator

I don't need to turn it up more like turn it down because a lad who tunes jap cars were I live said that when my car comes on boost it's really really rich and he said that's due to having a Walbro fuel pump In, I need to turn it down slightly and I'm not getting very good mpg
