i got the new snoot boots on... i can here more of a pronounced supercharger whine now than before but i get 13 psi wee tiny bit more boost goes up to 14 psi if i floor it in fourth gear but not in 1st 2nd or 3rd gear. i think it might be to do with the by pass valve now not too sure?? pretty miffed

Still an increase in sound and a small increase in boost?? Did ever try turning the grub screw out one turn??

Just wind it out slightly. Even half a turn and see if the butterfly follows it. If it does then yours is adjusted slightly open. I set mine so that the screw is only just stopping the return of the butterfly but not enough to hold it barely open. You can usually turn it with it in place with the short end of an allen key or pliers.

Other than that there must be leak somewhere else or your SC isnt in great shape.
