Apr low pressure fuel pump and fprv

[Darren Simpson]

Hi folks,

Question time! If I fit an APR low pressure fuel pump and 175Bar fprv will I need to have my car mapped again?.

Thanks for the advice.

Why do you want to fit those parts?

Cause I’m going to go for bigger turbo in the future, but I’m unsure if I buy them now is there anything stopping me having them fitted without mapping again?.

My understanding is the APR pump is a stand alone unit and will be fine without a tweak. However, that fprv is quite a high pressure version. Have you talked to your tuner about the total combination of parts required?
I was speaking to Nikki Gower a couple of weeks ago and he suggested RS3 injectors with the AKS head mod would allow the car to run with only an RS4 valve which runs at a lower pressure in combination with a TTE 480.

I have the RS4 valve currently, I wanting to go stage 3 as they call it with bigger turbo but want to start building the car now with what’s needed that doesn’t required to be mapped again by r-tech.

Looking for a list of what they want hardware wise fitted to the car and what I can fit prior to needing mapped, whatever is outstanding I would like to have fitted just before the map and trailer the car there for tuning.

When I asked about which lpfp, Nikki said TTRS/RS3
