Have you ever logged a run that hasn't shown this loss of boost above 6400rpms?

Does the transmission flash cause issues with not reaching boost target on 8 speed AT?

Ok so here are some logs before the turbosmart bov and intake inlet pipe.

After install.

So no measurable change? It still can only hold 16-17 psi above 6000rpms as before. I'm telling ya, it's the limitations of the stock turbo, head, and cams.

Do the ewg have a wastegate pressure converter or boost solenoid?

EWG = Electric Waste Gate

out of curiosity have you logged the car with your current setup on the OTS file to see if it is doing the same thing? try the 91 or 93 file and see what the logs look like

Would I get an error code if the electric wastegate was bad?

I did run OTS e30 tune. I still had boost loss but it was btw 1-2psi. My tuner said that the OTS tune request a lot less boost which is why the boost loss is less.

Yep.

Please post a log of someone with similar mods and stock turbo showing that boost is being sustained above ~6200rpms because I'm not finding them. I really think you're wasting your time and money tracking down something that isn't a problem.

Why not dyno on a Dynojet to get a sense of the power to see if you're actually low on power? A Dynojet will give you the most useful and reliable data to compare to others with similar mods dynoed on a Dynojet.

I plan to get it dynoed soon. I just asked BMW DIY GUY to see if he can share logs. I want to see if his car falls off like mine after 5k rpm. He has the same setup as mine minus the turbosmart bov and the intake inlet pipe. We are using the same tuner.

[oma3710]

BMW DIY guy only had log below which has with his active tune. He wasnt able to get a good log with his bm3 tune yet.
