~~Review by Jerry G 8/9/2024 :   Recently got your  Duramax no drill boost gauge port. This is an awesome part. It seemed hard to find you guys and this part online, but it’s great. I wasn’t looking forward to drilling the intake pipe. Even thought of trying to build something like this myself. I searched for a couple of weeks before stumbling across this in a google search, well worth the effort.
