I hear flow noise on boost
 

It sounds like it is a screaming banshee and quite loud. I didn't have it before but now it it loud any ideas what it might be and where to look. I dont have any apparent leaks between the turbo and the throttle body

Orange o rings seem like a good place to start. Assuming you still have them and don't have the long neck sleeves.
I guess an intake port gasket could leak/whistle under boost, but I'd bet you'd also have a vacuum leak and other complaints than just when on boost. GL

You have a blow off valve? Open vacuum port?

Waste gate?

How did it start? out of the blue? w/o any progression?

Do you still have steady full boost at WOT?

Boost drifts down sometimes from full boost but not always depends on how it comes in if I boost fast it drifts off but if I bring it in slow it comes up and stays up. I was thinking wastegate still troubleshooting. Will check the intake gaskets that is a possibility I do have a BOV open to atmosphere but don't recall hearing that sound before I am going to take the filter off and see if that makes a difference. Thanks for the ideas and responses. Don't have the o-rings and I have 15-16 in vac at idle and 22-25 in vac at cruise a search for a vac leak today revealed nothing.

The car is just plain running like crap it has no get up and go and sounds terrible very sluggish. I am curious if my O2 sensor is going bad that would screw up my EGO corrections and make the car run terrible wouldn't it? Both times I took it out for a drive today at about the same time the LC-1 started blinking 7.4 ideas?

I am such a dufus! I just looked at the target AFR table that is default in tunerstudio and no wonder I have popping and crackling it is extremely lean. Can anybody please post an example of their AFR table for MS3 that they used for VE analyze live?

This is roughly what I am trying to achieve. My car will run as lean as 16.5 but after that, it starts to surge.

Thanks

I think my O2 sensor is toast after going through the calib procedure after a few min. the gauge starts flashing 7.4

What brand/model of WB02 do you have?

Innovate LC-1
