installed gen 111 drag kit but no boost? any suggestions will be great? everything installed professionally but still no boost? there is an las trans on si becuz i blew the diff in the si trans? could that be the reason? also my wastgate has no gasket in between itself and the exhaust anifold, could that cause a leak? thanks

 

that could be it, im sure you checked all the piping to make sure the connections are good. if it was install professionally, who did the work....take it back.
