    Hi all,

    Hoping you guys can shed some light on my poor performing S3 :(

    I have attached the dyno run results.

    The car has a remap, the garage I went to flashed stock and then did a custom map as they said there were issues prior to flashing stock map.

    MAF was changed and they fitted a BOSCH one and I have had a n249 delete done.

    Hoping someone can shed some light :)

    Cheers.

    They didn't unplug/pull the fuse on the haldex... thats why the graph is wobbly.. bet it doesn't drive like that on the road... if there were issues prior to the mapping I assume they fixed the issues? what were the actual issues and what map?

    Any logs?

    Dyno Dynamic rollers don't do cost down... most of the time they only show wheel hp then use a guestimate for flywheel hp...

    Oh! I should go back and say that then right?

    Said there was a dodgy map (fake revo) and low power so sorted all that out. There were n249 codes as well so they did the delete.

    Supposedly they used a 4wd dyno.

    Haldex doesn't like some 4wd dyno's if the rears are driven at the same speed...

    Just pull the fuse (31) and run again...

    Just looked at the boost pressure too.... tbh the graphs suggest the car isn't mapped... 0.8bar or there abouts is std boost... torque and power looks std..

    At least car's running fine and it's not low on power. That was a concern. Feels fine when driving as well.
