This manual Golf R (upgraded clutch) has a BOSS500 and OEM fuel system when it first comes in. We reach the fuel system limit on pump gas and upgrade the HPFP.

We then add a bit more power on pump and maximize the turbo potential on E30.

The car at this power level pulls really nicely and has a great boost response
