Frpp Whipple Tune Voltage


Recommended Posts

Hey guys, getting a lot of conflicting info so figured I would reach out. I have a 2011 with the FRPP 750hp whipple kit installed. For the last year I have been trying to find out why my charging voltage has been at 15.2 volts. Been in and out of the dealer where they have changed alternators and even a new pcm, no changes. Recently Lund advised me that the FRPP tune bumps up the voltage to 15ish, Ford Racing denies this.


I would like to find out what you guys out there with the same set up are running for voltage so I can put this matter to sleep.
