Great external wastegate for a FP Green Turbo!

, Aug 3, 2009
Running this on an STI block with an FP Green turbo externally gated, and am very happy with the performance of the Tial Wastegate. The wastegate has over 100,000 miles on it and has never failed me. Great performance and value. Well worth the investment! A++
