i just replaced the stock turbo on my 06 MS6. The turbo is only pushing 9 lbs. of boost why is this and what do i do, it was pushing 15 right before the old turbo blew. Any help would be greatly appreciated.
 
Check wastegate rod adjustment ,but before ,check wastegate pressure using pressure gauge ,do this before u adjust rod .good luck.
