Default boost lag from my k03/16 clipped. what gives?
i'm not hitting full boost until about 4000 - 4200 RPMs. would an incorrect wastegate cause problems? i'm running N75 not MBC.

thanks

Default Did you try it with an MBC solo?
If you're using K03 software I'd *definitely* try that first.

N75 duty on K03 code can really make for some limp low-end boost with larger turbos.

If it doesn't spool with a properly adjusted MBC then you should look toward adjusting the wastegates.

MBC *only* or in parallel? Is there a bleed hole in the MBC?
