For those customers with the Greddy turbo kit or other forced induction setups, a slight power increase can be obtained by eliminating an internal boost leak. One of the two hoses leading back to the intake is the problem. We have been testing a simple one way checkvalve that can handle the heat/pressure and yet is a cost effective way to eliminate the problem. Please do not expect a huge increase in performance but a boost leak is a boost leak. They are in stock with instructions for $14.99 on our ebay Store

Thanks!
