hopefully this helps. when the airdog is installed, you pretty much need to max out the regulator on the airdog base, then nearly max out the aeromotive regulator. optimum desired Elite spec. PSI is 15 at the aeromotive regulator pressure test port. The airdog might not quite produce it. The truck this pic was taken on only put out 14, but that's fine. The two lines going to the frame rail need to be routed behind the L engine mount similarly routed to the factory solid lines that get removed. You may need to trim the heat shield under the LP turbo for the injection pump line to clear. Feel free to ask any more questions. I'll do my best to help.
