Project Transparency
Project Transparency is a project that PDI is conducting to fully release all known information in real time about fuel injectors, and fuel injection pumps. PDI hired a Third Party company as of February 2026 to perform tests along with PDI so nothing is biased. All Major Brands in the Performance Diesel Industry will be tested , including ours!
Doing this ensures full transparency in the industry, this is not to knock, or harm any companies reputation what so ever. whatever the results are please refrain from making any hateful comments to any company & its employees.
Again this Project is for educational purposes only – you are welcome to your own opinion and conclusion. we are just here sharing OUR Results based on what has been provided before us, or by us.
