3) Timing falls out at 2516 - 3275 RPMS is cause you are running too rich of AFR on the onset of WOT.

4) Boost and load is overshooting at 3k RPM. There is either too much VANOS overlap or too much adder or both.

5) Those timing corrections look like you need new plugs and coils. If your gonna run that much advance timing get NGK plugs and gap that to .022" . I recommend the new OEM BMW Eldor coils.

Boost curve looks fine after 3200 RPMs.

Thanks BuraQ.

That log was from the MHD OTS E40 tune. I am waiting on my Hexon RR600s and MMP inlets/outlets so I am not looking to "fix" the current tune...just trying to learn. Once I get the new turbos installed, I will be getting a Wedge tune.
