APR is pleased to announce the Stage II ECU Upgrade for the Golf R and S3 is now available for the North American market with other markets around the world to follow. APR’s Stage II ECU Upgrade is designed to work with APR’s upcoming Cast Race DP Exhaust System and builds upon APR’s already incredible Stage I ECU Upgrade. When combined with APR’s Intake System, peak power and torque figures grow further over Stage I to produce an astonishing 382 horsepower and 387 ft-lbs of torque! The additional hardware and tuning allows the turbo to spool much sooner, and ultimately results in a gain of 36 horsepower over Stage I and a staggering 100 horsepower over stock! APR anticipates the new AWD Cast Race DP System to be available later this year.
The additional power directly translates to a quicker vehicle in real world testing. APR was able to achieve a quarter mile pass of 12.8@105.7 MPH on an unmodified Golf R and as quick as 12.0@111.7 MPH at stage I with 93 octane fuel. By adding APR’s upcoming cast downpipe system, Stage II ECU Upgrade and 93 octane fuel, APR’s Golf R set a new stock turbo world record pass and shaved more than a second off of the stock time with an 11.7@114.4 MPH pass! This was achieved at Montgomery Motorsport Park in Alabama, an NHRA certified track, at full vehicle weight with APR 19x8.5 wheels and Michelin PSS tires.
