Hello

I have fuel pump from bmw. I am sure that this bmw pump is weaker than original rs turbo pump.

Can I have problem with poor running because of this pump?

I can set up boost higher but car is not pulling good.

Maybe too low fuel prressure?

 

Why would you want to use anything other than a Ford pump?

 

That's what I thought, either way you need to check the fuel pressure under load as well as static.
