Can someone tell me if i can use my p3 gauge with a flash? where do you physically connect it if there is no piggyback?
thanks

You only connect the gauge to a tune for map switching capabilities. All else stays the same if you have a flash tune instead of a piggy back.

Your P3 gauge gets boost pressure off the vacuum line that goes to the diverter valve, not the piggy back.
