VW Golf MK4 1.9TDI ASZ PD130 - Stage 1 remap + deep idle & popcorn limiter

This car is quite high mileage (216k) but it has been maintained well and still responded very well to tuning! The current owner has put a full "straight-through" exhaust on the car which has amplified the N75 Duty Cycle modification we use to achieve the "deep idle". If you watch the video below you can hear the deep tone and the increased spool-up sound this creates. The golf performed very well, with no issues picked up in data logging.
