I recently put on a corksport sir, downpipe, exhaust and forge BPV.

The first day at the shop I had the downpipe on no problem, and since its an easy install I added the forge bpv.

As soon as the car warmed up I took it for a spirited drive around the block and when I give it WOT in first gear the car jerks and the BPV empties.

This will also happen with a downshift from 3rd to 2nd and giving it WOT.

I swapped back to the stock BPV and I'm still having the same issue.

It feels like its not holding boost well? I checked all of my lines a second time and everything is secured properly. What am I missing?

Suggestions? Please help.

maybe fuel cut???
Ive heard of people getting fuel cut from just a downpipe.

Is it pretty violent when it occurs? Demon is probably right.
If you don't have a MAP clamp, AP or SB then you are probably overboosting.
Is it a CS DP? Hope that little separator tab they put in there between the divorced WG tube and turbine tube isn't getting in the way of your WG flapper.

did you give the ecu time to relearn fuel trims? i couldnt imagine going wot right after install would be a good idea, especially with serious mods like dp.

if you don't have the upgraded fuel pump then it is fuel cut
