Hi, need your opinion on this...

I just finished installing a RRE upper I/C pipe w/ a 1G BOV, and a manual boost control. Something is wrong... The car loses power and just lags when turbo reaches 3500 rpms on 2nd and 3rd gears. I have tried all different settings on the boost controller to no avail.
What do you guys think is causing this/ how can I fix it? Thanks!
