VWBoost member hits 473 wheel horsepower in his MKVI Jetta GLI with modified APR Stage 3+ kit and USP Motorsports upgraded LPFP
Congratulations to VWBoost member pattrick02 whose MKVI Jetta GLI put down a very impressive 473 wheel horsepower on a dynojet dyno. This car has a modified APR Stage 3+ upgrade but really it is the fueling upgrades that make this amount of power possible. The HPFP (high pressure fuel pump) and LPFP (low pressure fuel pump) system were both modified by USP Motorsports in order to give the fuel system enough of a bump to support this amount of power.
The upgrades to the LPFP system were to add a second in-tank low pressure pump. The high pressure pump was modified to flow more efficiently. The other changes are a new tune and MS109 race gas. The head is still stock so there is still a little more to extract from this setup and cracking 500 wheel certainly is feasible.
Very nice work @pattrick02
