Turbo lag and BPV's......

If you want to rid yourself of turbo lag, then get a bigger downpipe. Turbo lag is highly correlated to exhaust backpressure, not the BPV. A larger downpipe will also give your engine the added benefit of lower EGT's - your exhaust valves will thank you, amongst other items. Don't expect to get greater power, just quicker response. A JT 3" downpipe is a little more than double what a Hyperboost costs - money much better spent. A Hyperboost isn't really necessary until one has done software/boost (>16 psi) changes. And if you have greater than 20 psi, make sure you get the Hyperboost with the heavier spring.
