When i launch it and shift into second the 2nd turbs doesn't come on and then when you let go off of the gas you hear a whooshing sound

 

Need more info. What's the boost pattern in first gear? Second gear? Do you have an aftermarket blowoff valve or his your stock one vented to the air?

 

i reach full boost but when i shift into second the car usual revs to around 4or 5000 rpms and the second turbo doesn't spool up and makes a weird whooshing sound like a owl, I have a blitz blow off valve

 

power fc set at .8 and thats what i get out of the first gear second gear when you whale it out of first it doesnt even spool to the second turbs

 

Ive had a problem similar to that the second turbo did not seem to work and it was making that woshing sound. Turned out my second turbo was still working but the Y pipe hose was torn and when the second turbo would come on the added airflow would cause the boost too bleed past the torn part of the hose making that funning woshing sound. Also I was only getting about 7 pounds at WOT in third which is why I went in search of a boost leak. Hope that helps.

 

Yeah i checked all the hoses on the y-pipe,all the nuts onthe intake pipes downpipe bolts and it still makes that wierd *** noise and it is frickin annoying.SOme days it doesn't happen and 20 minutes later it happens again.What else could it be possibly be my bov
Thanks
