Is this dyno graph good or bad?

    Was on the dyno today for my 1.8 TT MK3 and it’s pulling 245hp & 390nm (Stock 180hp & 250nm). Only had a stage 1, K&N filter panel and resonator delete.

    Pretty impressed with the results but was told it doesn’t look good so would like to know people’s opinions. Thanks

    Don't know about the actual numbers but people are probably seeing the large spike on the torque st 2700 RPM which could be mapped out with some more time. This also gives an artificially high torque figure as the peak of that torque plot is what is measured. This sometimes translates to more wheelspin when accelerating in lower gears as the rapid increase is more likely to break traction . If it's quattro won't be an issue though.

    Yeah the spike is what people are concerned about. Mine is FWD and it really struggles to keep down power in 2nd so that could be why. I guess it’s back to the mapper

    Could it be a possibility that the spike is from wheel spin?

    It is possible the car lost traction on the dyno but if you look at the torque plot it almost vertical at the point when it peaks. This translates into rapidly rising boost pressure from the turbo that probably spikes and then is brought back under control. This is what can be mapped out to a certain extent. It would reduce the peak torque number by a small amount but makes the car better to drive.

    Thanks for the help. He’s going to see what he can do but without a dyno to test on it’s a tough one to fix
