my performance plan for the Tsi

[TurboDomestics]

Yeah, but with a 255lph pump you'll need an AFPR.And for 250 whp, the 190 would be fine, assuming you dont want to upgrade from there.

So basically you'll need in addtion to the mods you've listed:

-550cc injectors.
-Apex'i SAFC2.
-And you should consider Hard intercooler pipes.
