Just had my Vauxhall Astra remapped, and the difference is unreal. The car feels much more responsive, pulls stronger through the gears, and overall drives smoother than before. Power delivery is spot on and it’s made the car far more enjoyable to drive. Really impressed with the results and would definitely recommend it to anyone thinking about getting their car remapped.
