I have an Elite wastegate. Plumbed right. I plugged the two open holes on the controller and the extra one on the BOV. I cannot get the truck to build backpressure like it should. At one point it would get up to 60 on the bp. Then... basically i cant get it back. Its like the adjustment has no dramatic effect. Either way you turn it. Also the wastegate controller makes a squeel/teakettle noise sometimes. Any ideas?
