Replacement fuel pump

hi all, just upgraded to bigger turbo, added secondary injectors, running standard boost and planning to boost it up. Is there any direct replacement from Bosch for the fuel pump for the TT to support the additional fuel needs? (like for a stage3+ catering pump?)
Or any suggestions of alternatives or experiences would be appreciated.
thanks!

I think the only real replacement is a Walbro 255 gph pump.

Hope I that is right.

What turbo have you uprated to? Why did you go secondary injectors instead of

swapping out to just larger injectors? Have any pics of your new set up?

Most likely running a piggy back ECU

to control the second set of injectors. This way the second set does not come on till after boost hits.

Something like a Blitz controller? I see that you're running a custom turbo,

is it a hybrid of some sort?

If it's like the A4...

then a RS4 pump is an option ($$$$, but still an option)

I have a Walbro 255lph in my A4, it's not a straight drop-in, but it's really not all that hard to do.<ul><li><a href="https://forums.audiworld.com/performance/msgs/44541.phtml">https://forums.audiworld.com/performance/msgs/44541.phtml</a></li></ul>
