Just completed testing of an Ag Solutions Module by PSI Power on my 8.3 ISC cummins. The model they sent me based off of the engine info I sent them was the 12200. Once installed it worked in stock mode with no issues. When I put it in the 15% or 30% mode, which are the only two other than stock that it can be in, the truck would die out and would not build more than about 6psi of boost when you stepped on the throttle very hard. So in affect it actually had less power with it turned on or up that it had in stock mode. I could not accelerate going up hill and go faster when it was on anything other than stock mode. I called for tech support and did what they suggested to no prevail. They did issue me an RMA for a full refund. There really wasn't much to it as it just plugs in to the injector lines and map sensor so other than checking plugs, power and ground connections there wasn't much more to the troubleshooting so I will just leave it stock as it has pretty decent power for what I pull.
