2017 GMC in tank pump Walbro 525
The in tank fuel pump can't keep up with the LT4 injectors and hpfp.
Upgrading to the Walbro 525 wondering if anyone has adjusted there pwm tables for the hellcat pump?
If so please share.
The current beta will not allow me to cycpe threw all of the unit options. Pulse per minute is what I think makes the most senss.
But I'm sure the 525 wont need to run nearly as hard as the stock pump did.
I guess I'll install and log. Then lower the ppm by 25%
Or if it holds the right pressure I'll just leave it alone.
These new fuel systems are non return so it may be interesting.
