Default First time log submission for review - 04-12-2021, 09:00 AM

I have a 2010 z4 with the following mods.
Pure turbo stage 2 DD
2 inch silicone inlets
Dual cone intake
Precision raceworks ignition
Stepped wagner FMIC
FTP charge pipe
Turbosmart diverter valves
1 step colder plugs
High flow catted *********
Eisenman race exhaust with secondary *** delete
Jb4 with your backend flash and settings for hybrid turbos

I am running 92 octane, and use this car as a daily driver.
I have 2 3rd gear pulls with the traction control and kickdown turner off attached. Running map 2, but i am getting overboost and kicking into map 4. Looking for adjustments. Thanks.

You're getting some overboost at tip in. You may need to adjust your duty biases a bit lower in that RPM range...maybe start with 1500 set to 42 and scale up by 2 and drop your FF to 80.

Okay, still overboosting a bit...try dropping FF to 50 and see how that looks.
