A returning customer brought us his 2008 Audi A4 2.0 TDi 140 in for one of our eco remaps. This one came in only making 115-120bhp (98.6bhp wheel power) as it had a blocked diesel cat. Once remapped and run on our dyno for a few hard power runs, the smoking stopped, (diesel cat cleared) it pulled 153.6bhp and gained 44ftlbs. Not a bad result for a full eco remap. Good gains in mpg to be had on this one if driven correctly too.
