, so I got an aftermarket turbocharger and the wastegate actuator measurements were reset. Setting it up proved to be a huge headache as it's quite difficult to get reliable readings from anything other than HDS. Instead, I took this pup and installed it. It is in the correct pre-installed position and is easy to install. At startup the check engine light P003A is off and I blow again! I have no idea why this is so much cheaper than the other options, but it seems to be working as intended. If something goes wrong I will update this review π
