Ok guys I need a little help! I have a 2002 Dodge 2500 Ext Cab. 5in lift 35in BFGs spicer drive shafts Mag Hytec diff covers air intake 4in straight pipe from turbo to tip. I have Edge Pro Comp but I cant use it right. I fried my VP44 with it already. I want to upgrade my fuel system but I have no idea where to start. Every says go FASS pump or or a Walbro GSL392. Which one is better? And how exactly do you install them? just between the pump and tank? Im clues here? If i upgrade to one of those will i be able to pull my truck at truck pulls or mess around on the streets on level 5 with worrying bout spitting death codes?? Im just not sure what i need. Help me plz!
