If you can keep the boost at stock levels (why would you want to do that?) then the fuel pump should be fine. But you're going to have a hard time keeping the boost down with even the S5 turbo. Assuming the exhaust ports were also done, and you have a decently sized exhaust, you're going to easily overwhelm the wastegate.

get a standalone and have it professionaly tuned. also for now i think you will need larger secondary injectors. trust me on this one. i should of kept the safr and saved for a standalone. but standalone is the ONLY way to make it reliable. ask BDC (he tunes half bridges with large turbos, with good success)

yes i used the safr with a half bridge. not a good idea but as long as you dont run on it forever and get the standalone and take it easy you should be ok for a while as long as its tuned properly. then i got the safc2 and **** hit the fan..
