I just installed a FMIC and 2" piping with a turbo xs bypass valve. It is recirculated. Now Im hearing a loud whistle, sounds like the turbo spooling up. It only happens when boosting while in the petal. Is this normal? I just want to make sure nothing is wrong. Also my boost seems low. I was boosting 7-9 with the top mount intercooler. now Im boosting 6-6.5. Maybe I need to drive it to let the ecm relearn??????? Thanks for any input..

I did fix what I think was a boost leak. I retorqued all my IC piping connectors and they had loosened up quite a bit. After that It ran much better and the whistle sound is pretty much gone. I was boosting a little higher around 7. I removed all the bolts from the wastegate and installed 4 washers between the wastegate and the turbo housing. WOW! Now I hit 10 psi every time. What a HUGE difference! Thanks for all the advice...
