clutch slip symptoms?

https://datazap.me/u/j555rt/gear-3-pull?log=0&data=6

My car is currently on a stage 1 acn tune from bm3 and has a catless downpipe. I feel that it is the clutch but just looking at second opinions.

What issue are you having?

Rpm and vehicle speed are consistent which tells me it's not clutch slip. If it were slipping I'd assume to see rpm increase quickly without rpm.

So in every gear above 3rd it revs up and then drops. This pull it only did it slightly. But if im in 6th it does it almost instantly

Is that the blip Early in the log? If so, that seems to correlate with a drop in throttle angle which I don't think would occur during clutch slip.

I would expect clutch slip in the low gears as opposed to high ones, too. ..

During your blip throttle angle drops I think to control boost pressure ba target. Mine done something similar. PTF said it's nothing to worry about. Best bet is to send them your logs and description to see what they say.

Is there a way to check the throttle position sensor?
