Have you carried out the ASM mods yet?

Yep,

Looking back at my logs it was doing it before the 5120 hack also, just hadn't really noticed it.

The Audi TT V1_1_20210204_132414 Trimmed.csv file is with 5120, the Audi TT V1_1_20200918_093419 Trimmed.csv is without 5120.

Looking at the screen shots you can see the vehicle speed wobble just before the throttle plate closes.

It's a Quattro and it feels like the front wheels are spining/slipping not the rears, not sure how the vehicle speed is calculated for the logs, one wheel, front wheels, back wheels, combination of all wheels or from the gear box?

I tried it with ESP on and off, same result, I did read that some of the ESP implementations activate at 40/50 KPH even if the ESP is disabled by using the ESP button, not sure if this applies here?

My initial though was Torque intervention but on the non 5120 log you can see the engine load is below the load requested and specified.

Not sure what negative deviation you are referring too?

Thanks

Yep,

That's what's brought the issue to light, I'm dialling in the boost, started far to low, then went far to high now reducing so I can get to the point where I was before the 5120 & new turbo.

It's a MK1 TT 225 BAM Quattro and it feels like the front wheels are spining/slipping not the rears.
