2017 BMW X3 35i sport with 97k miles on it. New to forums and new to MHD Forum - My X3 currently has Burger intake, burger intercooler upgrade -DV & GFB DV Upgrade MHD Stage 2 w/93 Octane gas & xHp transmission flash. I have been chasing a mid to high RPM WOT power surging issue. I have replaced boost controller, vacuum lines for turbo/boost controller, Used Fabian @PureBoost tuners to see if it was MHD issue and recently did the DV diverter valve with the GFB upgrade (not using the optional spring-done want to risk a code) and still having issues. I have added a link to my log from today. This car pulls hard but you can feel you head/neck surging as it seems power is being pulled out for some reason. I also have zero CIL or codes, which makes this difficult to diagnose. Would someone look at my log and give me a clue what to check now?? Thank you -
