I see a different result when I turn my boost up to 25 and part load the motor at 15 vs tune the wastegate at 15. Is this a difference in ve due to wastegate? Or due to ve changing from part throttle bov venting? Or maybe the condition I'm experiencing is in my head and it's the day to day differences.

Using an o2 dump

Thanks for the thoughts!

 

Part throttle will definitely change your VE. That's what the throtle is there for, it's a user controlled intake restriction.

 

Oh crap wrong section meant to go in ecu flash.

Thanks wreckleford I was thinking that map is map. It isn't far but starting off tuning wastegate pressure is how I wanted to prep my high boost setup. I notice that once I turned the boost down I had to retouch my ve map to be richer down low and leaner up top to work with 14-15 wga. Only off about a half point and it seems that there are other factors too

Smooth throttle is my goal so that's why my bov does vent kinda easily at part load ... Greddy type s.
