oh that flat spot! If its the one that alot of people are suffering from its around 5200rpm. Still not 100% sure why the cars do that but revo dont have a clue either it seems.

Do you know what settings you are running. Are those figures on AMD's rollers?

I think its because of the way they dyno it. Some cars will only do it under certain conditions.

It really is ****ing annoying though, especially how revo dont seem to care in the slightest that alot of cars are affected by it and dont offer any assistance and insight into the issue.

As in your revo settings, boost, timing and fuel.

AMD mapped my car but I have the revo switch to adjust settings.

You have the basic map but you can adjust it to suit your needs and the environment.
