Resolved Why do the Fuel pump rewire?

[Wpgdsm]

What is the advantage to this mod? Is this worthwhile to do to a stock TSI? What kinds of gains if any could I expect?

 

[Spooling99]

re-wireing the fuel pump helps the fuel pump maintain a higher fuel pressure by allowing more voltage to the pump itself because the stock one is pretty small.

That's pretty much right. It allows voltage to stay constant at higher RPM. At high RPM the fuel pump only receive's about 10 volts instead of the full 13. This helps it maintain consistant pressure at higher rpms.

About the rewire: Unfortunately, there is no defenite answer on how much gains are acquired. You can run a bit more boost but first get a tuning device and logger.

Thanks for the input. I look into doing this for my car soon.

I would turn the boost down a little and get a logger to see what is happening.
