How good is this little gem??? Turbosmart has invented a tool that measures the lift of their external wastegate range…. In the past, a lot of us tuners have always had to estimate spring rates, wastegate size and boost controller duty cycle to get to the correct target boost. Not any more!!!! We are now stocking these caps and the appropriate sensors here at PZP. Best of all they fit all of the current wastegate range so no need for upgrading your trusty gate!
