check engine light
 

I have just bought a 2012 Dodge Ram 2500 back in January and have just installed a performance chip from US Diesel Chips . It has a switch that you can use to turn back to stock. When I drive my truck about 1 to 3 days the check engine light comes on and I get a code P0101 after I clear the code it comes back on again. Does anybody know how to stop this or is it normal ? Should I send it back to the company and get another one or refund? Any help would be appreciate!!!!!!!!!!:banghead
