Audi S6 4.0TFSI - RETUNE of Awful Map

Stock : 420bhp / 550nm

Old tune - let’s not go there

Mapro - 540bhp / 880nm ECU and TCU

When this one arrived it would cut out randomly , stank of fuel and was running so rich it wasn’t even funny , not to mention the underboost 🤦‍♂️

We very nearly kicked this out and said we aren’t tuning it BUT Ryan wanted to see what happened when it was flashed back to standard -

An absolutely faultless run with good fuel trims and boost on point meant the map which we already knew was poor was in fact causing a whole host of issues .

Once we retuned the Ecu and TCU correctly the difference was night and day and one very happy owner .

Big thanks to the owner for grabbing some pics as we totally forgot 😂
