Yup you right, but i just found it for 190 http://store.titanmotorsports.com/bo044fupu05.html..

I think thast the way I am going, put it in and be done, unless this is just a tuning thing..

what a pump will support is based on n/a and boosted for example , boosted setups need to run richer so they need more fuel meaning the pump will support more n/a hp than it will boosted hp.

also running out of pressure isnt your problem, your running out of volume. your fuel system is only as good as the weakest link.

so going to dual intank walbros will solve your issue. your feed line may be to small . i forgot how much the stock feedlien will support but id upgrade it to a -8 an line.

my fuel system consist of dual intank walrbo pumps, one wired to turn on at 2 psi . -8 feed and - 6 return since i had to make it a return my truck being an 04 came with a returnless.

i am running it boost referenced so at 15 psi boost im at 73 psi fuel pressue. its working great thus far and will support 1000 boosted hp.

modifying your cup to hold the extra walbro will be about the same amount of work as making it fit the bosch.

I really hope it isn't to the point where I have to go and change fuel lines around. I don't think i am making anywhere close to that power. I think I am going to try out the B pump. I would have to buy 2 walbros, don't mind doing the work to get the B to fit. This might be something that could be corrected with a tune change, I dunno for sure at this point.. Thanks for giving me the info. Did you set up your system, to work how it is??
