Boring. I think you should price out a stock pump then price out a modded pump & weigh your options. I saw a guy sell a never used HRVP on here for less than what a stock replacement costs. They're not cheap either way & if you replace it with something beefy the first time you won't have to do the 3.5 hour job again when you want a bigger one. It'll only put out as much fuel as it's told to anyways so it's not like it will be excessive.
I'm on a stock tune now & I feel a 100% difference when my truck hits lock up now than with the stock pump.
If something breaks, replace it with something bigger. Tires wear out, put bigger ones on, lift pump goes (which it will) put an air dog on, drop an injector, drop a set of bigger ones in it and if you ever have to pull the trans never ever ever go back stock hahahaha. The aftermarket prices hang right there with the OEM ones which are insane. I work for Dodge lol.
