I think I am sold on a dw300. I have even read of guys having great luck without even hard wiring them. Stock fpr too!

Do you think that it Flows more than the unmodified Walbro or the modified (relief valve punched in) Walbro?

Two questions. 1. What is the amperage draw difference between the 044 and the aeromotive? 2. have you guys tested the OEM denso pump from a supra tt? It may date me a bit, but back in the days they gave amazing results in my 2g gsx.

The amperage draw can be seen in the 2nd graph.

I have not tested any supra pumps.

I used a Denso/Supra pump in my 91 Dodge Stealth R/T TT and compared it to the Walbro. What I found was that out of the box the Denso at 14v did slightly better than the Walbro but when I pushed the voltage up the the Walbro started to out pace the Denso. Currently I'm running the single Walbro at 17V with the Kenne Bell Boost a Pump making 550awhp on pump gas. (twin 16g turbos, stage III head etc...)

I've had the Aeromotive in my 35R 93 octane Evo since they came out and I haven't had any problems yet. It's definitely quieter than any Walbro I've ever used.

DW300 and a hardwire will get you to the mid-500's out of the box. If the engine is built to push the red for all it's worth, you'll need to get 18v to the DW300 so it can supply the amount of fuel you'd need for a safe 600+.
