I'm thinking about installing a walbro 255 hp in my 93 tsi awd, but i was wondering if this mod will actually result in any horsepower gains since i'm still running on my stock 14b turbo. I know that i'm gonna have to get an afpr.
my current mods are:
-2.5 downpipe
-2.5 exhaust
-2.5 test pipe
-Rewired stock fuel pump
-k/n filter
-mbc@15psi
-uicp
