[QUOTE="dsberman94, post: 1536394, member: 12667"] Run a buzz test, key on engine off test, with ae. If that fails you’ve got a wiring problem or bad idm. If it passes replace the cps For piece of mind. Pull the hydra chip completely out and see if it helps. The code says there’s a communication problem between the pcm and idm. Nothing to do with the turbo or wastegate at all. [/QUOTE]
