Uprated hpfp really only needed for stage 2+ tune on a k03.
I am getting flashed to APR stage 2 tomorrow on my 07 GTI. I have a extra pump packed and ready to send to APR for a rebuild...its $550 for a rebuild...but I want to know if it is worth getting it done...anyone have any thoughts either way?
Went stage 2+ april 2nd, it's definetly worth it. The car wants to keep going faster now. One thing that i wasnt told but found out later on these forums is our MK5's has a (PRV)-Pressure Release Valve that must be replaced since your APR HPFP runs a higher fuel pressure than OEM.
Here's a website with all of the info about it.
