not stutters, doesnt fell like timing is being pulled, but the BOV goes off and the car feels like it hit a brick wall for some reason,, only in 5th gear, will completely dump alll boost at 4k rpm..tried searching, but no one really has the same prob. pretty much have a 3" turboback, injen upper ic/intake and greddy profec B spec II, HKS SSQV recirc. it dumps for a split second and starts spooling again

 

bov leaking?

 

u have a boost gauge? is it spikeing? it sounds like boost cut.

 

doesnt seem like its spiking, and i dont think the bov is leaking...it literally dumps ALL boost adn starts spooling again...

 

fuel cut when your boost spikes

 

you need a boost gauge to see how much boost your hitting.

 

That sounds like fuel cut to me....I hit mine on occassion..dunno why...
