These costs are tough to swallow. Really tough. Basically to really benefit you need a bigger turbo to justify the bigger fuel pump.
I feel like a safe 460-480whp would be a riot in a well setup 2 series. More so the M2 as it can fit a little bigger tire. Approaching 500whp would be icing on the cake.
Unfortunately, it's quite the endeavor to get there. $2300 fuel pump, $2500 turbo, $600-ish in other install bits, plus whatever your labor is or a shop's labor is.
$5500ish is a lot of money.
