2 separate businesses from what I understand. Glenn does engine builds, installs, parts, actually runs a shop. Chris does machining and builds turbos, that's it.
I did replace with Bosch Motorsport injectors, and I still get the same codes. I replaced the injectors, cross tubes and upper gasket with the connections on it. And still sometimes when you floor it falls on its face and runs on 3 cylinders. Shutting it off fixes it until next time. Truck has edge juice attitude CTS
