this is a good idea, and i have two 044 in line as we speak, it seems not to be a good idea to mix pumps, according to some of the info i have seen, maybe use two walbros?
also info i have gleaned from other sites seems to indicate that using a feed pump will increase the available pressure of the working pump significantly, but wont increase the flow rate by much.
Bosch do a higher pressure pump than the '044' but it is still rated at the same flow rate, just does the volume at a higher pressure.
increasing the pressure will also make your injectors flow more, thereby making them artificially 'bigger'

yeah i have seen what you mean, but i 'hope' the figures quoted are with the check valve in place, i removed it from the first da31 i used, and it died after about 1000 miles, the guy replaced it, and advised me that pump needs a 15mm inlet pipe and the check valve in place to allow it to run as specified.
the new one only lasted two days! he reckoned it was down to the inlet pipe being too small, as all these type of pumps dont suck well, they push the liquid.
maybe removing your check valve has upped your pumps output, but it will probably strain it more?
