i got fuel pressure drop after installing my magnacharge i was told that you cant install an aftermarket fuel pump. so i changed my fuel pump to a stock 1 and i still have a drop to 18-20 psi when it boosts.

I need a solution will a walbro work im thinking of installing a double fuel pump but will it go to the safe mode (power reduced) im stuck with tis situation from 1 week now and the tune is perfect cuz the problem is from the fuel pressure drop.

 

maybe im missing something but why cant you run an aftermarket pump in line?

 

alright the truck is at the workshop installing a double fuel pump, will know the result today hopefully
