3rd time lucky for this car and its owner before ending up with us at the Tuning Lab. This car has been tuned by 2 different local mobile mappers this year but neither could get it right but still charged. Also an obvious mechanical issue was missed by both (We aren't just a tuning garage we build engines/service cars/change cam belts etc and work on them everyday). Originally booked in for dyno testing because the owner wasn't happy we soon found it to be making poor inconsistent performance figures and really lacking driveability. Binning off the previous map we started a fresh and had it all sorted in no time. Audi A4 2.0 TDI PD170 stage 1 remap.
