325 w/ no core is fantastic, and I haven't heard anything bad about Pensacola Diesel. If you want more out of it you could check with Mel Agne (agenem) from here for a "Moose Pump" but it would be more. Ken at DPS offers a turbo cal pump as well for cheaper, but he's had a few pretty serious customer service complaints. Mel's a safer bet, but Ken is cheaper by a couple hunndred. Both pumps are allegedly much more capable than the standard off the shelf DB2. If you just want stock, you're not going to beat 325 outright, no core...even with a core required that's pretty good.
