performance problem

[patsdsm]

i am having trouble with my car and dont know what it is so i will try to explain what happens and maybe someone can help me figure what it is. my car runs fine until i try to spool up my turbo like say i will be in first gear pin it and shift into second as soon as i get into second the car dies out on me and takes a few seconds for the car to spool up again and it does this after every shift but only does it when i shift gears. it doesnt lag when i am rolling in a certain gear and pin it its only when i go to shift gears is when it dies out and has to build up momentom again please help

Is your BOV venting to atmosphere?

That or FPR overrun. Why you keep opening new threads instead of updating the old I have no clue? http://www.dsmtuners.com/forums/showthread.php?t=203947 If you have a problem with me posting in your threads due to the run in I had with your buddy in the other thread, just PM me and I'll stop posting in your threads, really no need to open multiple threads for the same topic.

yea it is venting to the atmosphere but it ran bad before i did that. i also did a boost leak test last night on my car and i have a boost leak on the intake manifold gasket could that be the problem that all the boost is leaking out of there while im changing gears and then it has to build up boost again to get its power back

Between shifts your BOV vents intake pressure pre-TB and Post turbo btw shifts and your engine will go to vacume (i.e. (-) pressure post-TB since the engine is still consuming air).

Yes it will help your car run better, but your problem with the "stalling btw shifts" is the BOV purging metered air (i.e. your engine runs pig rich and stumbles)
