BMW X6 Turning causes RPM Jump

Hello,

I have a tuned BMW X6 35I with catless Downpipes. My questions is this. Whenever I turn left, occasionally the rpm is fluctuating. My usual Idle is 600 RPM. But when I turn left the rpm jumps between 600 and 900. That only happens when you start to drive off and have to make a left turn right away like in a parking lot for example. Turning right does not seem to be a problem. I know your steering pump is working and its normal but I was wondering if having an ECU tune + Catless DP's cause the more abrupt RPM jumps. No codes and the car otherwise seems healthy

P.S. The RPM surge while turning left seems to be only occasional.

Thank you

sorry to be off topic
but what brand of catless dps are you running?


Im also tuned but stock cats, I dont think I experience fluctuation of rpms

what i do experience is when doing full turns left or right
there is jerkyness on the transmission

seems like xdrive cannot sort itself
has been like this (before the tune) ever since I could remember

Look into failing transfer case. Apparently its not uncommon for them to go out. Its what controls the torque vectoring and xDrive so you will notice it when turning.
