When I turn up the boost I dont hit fuel cut off but when I shift my engine shutters like fuel cut off and then runs fine. Any chance thats my Bov not allowing enough pressure out before I start back in gear?

Thanks

What kind of bov? If its venting to atmosphere then the engine isnt seeing the air that measured earlier, therefore its really rich will make it almost die or die sometimes.

where does your boost controller get its boost reading from? in my experience, if you use the manifold boost instead of the turbo nipple for the boost controller, it spikes between shifts.
