2002 7.3 towing problems

[vegasrjr]

I just completed a 2300 mile trip. When I left home with tow tune installed the first hill I encountered , the engine light came on.. I pulled over and ran diagnostics and had a 0603[/u] error code.. This predator is only 2 weeks old and it boots up Ford _7_3_ Rev 8r02...
I cleared the error and continued on.. within minutes going up another hill I got the engine light back on , so I pulled over off of I-40 and ran diag. again same error cleared it and ran till the next hill same problem.. I installed the stock tune and the light never came on again in 2200 miles of towing a 10,000 lb
trailer... This 0603 code is not one of the expected codes Diablo lists can you help as my fuel mileage is poor....Thanks
