I am thinking, I am not getting enough power to it via the stock harness/wiring. He is sending me another pump with new wiring harness.
Even if I get the same results I am seeing now, I have to commend Jay for standing behind his products. I won't likely see the dyno again till may or june, but I will update.

even the results from other platforms seem to be lacking and I know ppl are using them.
I would think that it would have to be a big difference in overall whp to justify basically 2x the price of a standard gss342 walbro. Esp considering that most kits need prtty high octane to run >600whp which a 342 can take you to.

that sucks.
I just want a pump that will carry me upwards 600whp.
Sounds like the DW300 has more advantages than just peak WHP.
My base FP is in the 50psi range at the moment but I will be dropping in some 800cc deatschewerks which will lower my base FP and thus increase my LPH output.

you could always do that with a 85$ walbro and a 230$ 20A boost-a-pump. that will run about 320LPH at 55psi. So run a 35psi base FP and you can add 20psi on top of that and support 800cc injectors at full tilt.
The DW alone runs 320LPH at 40 psi, so if you only needed 5 psi to get to your HP, that would support 800cc injectors by itself.
Get a 200$ DW301 pump and 230$ 20A boost-a-pump and you can run 1000cc injectors at full tilt up to about 60psi.
Of course this is all rough math, but viable alternatives to going $$$ twin pump.

can you cite 1 example of this? I couldnt find 1 example over dozens of forums and a ton of threads on BAPs. All heresay without any proof of actual failure.
besides its not overdriving until you are boosting at whatever PSI you want o have it come on at. DW rates their pumps at 18V right on their spec sheets as well.
You could probably string it out to 500ish with E85. But why cant you make 500 on pump 93 octane? Thats not very much hp. The horrible gas mileage doesnt even make E85 worthwhile unless you are making well north of 700whp. At that point, twinpump or bigger is needed.
