Hello, im still getting my 1 ton back on track from the previous owners screwups. Ive noticed after 2000rpm theres not alot of power, or doesnt seem to be, but anyways i started looking around the engine and found on the wastegate theres two nipples side by side which im assuming should have vacuum lines hooked up, but theres nothing. Im sure this is affecting my power problem, i just dont know where the lines come from or go too. Any help is greatly appreciated, Thanks!!
