Just installed the treadstone 340lph
Super simple install. Comes with new fuel sock, flying lead (not needed) 2 clamps, 5 inches if fuel line (not needed), fuel pump insulator ( not needed ).
Had a slight high pitch whine... But I had to put my ear next to it to hear it. Much quiter than my walbro.
For 118.00 shipped (MAPerformance) you can beat it!

Would like to see if independent testing of the Treadstone 342 backs up the manufacturer's claims:
At 40psi of fuel pressure, the pump is able to deliver 340 liters of gas per hour (lph) 25% more flow than the standard walbro 255lph or TRE255 pump, and 12% more flow than the Deatschwerks.

i dont know how to test it or i would.....
and right now i can start the car because i just installed new fic 1100 high Zs. and im at a stand still cause im not sure if that rubber grommet goes between the rail and the injector likw on low z injectors.....

So I've purchased a Treadstone TRE342 pump from MAP and given it a try.
I found that I could not get the TRE342 to prime with the usual method, like I've had to with the DW300 in the past, as described here:
http://www.coordsport.com/blog/2011/...allation-tips/
- without running voltage to the connectors at the top of the fuel pump housing from the battery. This may have been because my 4-year-old Odyssey PC680 mini battery has gotten weak and can't supply enough voltage (but putting the battery on a charger set on the 50-amp "engine start" setting didn't make any difference), but I've never had this problem before with other pumps. For the record, the wiring I used to prime the pump directly from the battery terminals was 12 gauge, not thin speaker wire.
So, after a little wire probing with my multimeter, I determined the positive and negative terminals for the pump, shown here, in case it's helpful to someone else:
The Treadstone pump did prime immediately (within a second and a half of applying voltage) when wired directly to the battery. And my car started fine after I primed it this way. But it sure was frustrating for the hours that it took to figure out WTF the new pump wasn't working... deinstalling the fuel pump to test the pump by applying voltage directly, than checking the wiring from the pump to the top of the fuel pump housing, then checking every fuse I thought might have been blown, then using the multimeter to determine there was indeed voltage coming out of the OEM wire harness under cranking. In retrospect, I should have reversed the last two steps in my troubleshooting... I guess I was hoping for an easy solution (blown fuse).
Test driving the car with the Treadstone 342 pump on my usual loop, which involves several 2nd, 3rd, and 4th gear WOT blasts, I saw that my AFRs had gotten .4 to .5 richer as compared to the DW300 pump I had in the car before (no other changes, other than obviously slightly different ambient air temperatures). I'm running E85, and I am utilizing the stock fuel pump wiring (i.e., not rewired).
So, based on my experience, it would appear the TRE342 pump is indeed capable of a bit more fuel delivery than the DW300 as claimed, at least with an Evo utilizing the stock fuel pump wiring.
NOTE: The TRE342 pump is slightly longer (just under 2mm by my measurements) than the Deatschwerks DW300. This means that while it does still fit into the OEM pump housing with the black rubber insert under it, it's a tight fit and a little tough to get the white plastic bottom retainer to clip on.
A couple pics, comparing the TRE342 vs the DW300:

i had the same problem getting mine to prime with mini battery and using stock wiring. That thing sure does need a direct wiring kit thats for sure.

re wire kit because this little guy pulls alot of voltage so its a good idea to give it its own power source. when you you do the rewire kit you will most likley over run the FPR.
