I ordered and received the VA-DG03 from Jannetty Racing. I am looking for a little help with towing and thought the VA would be a safe route to go. The box installed easily but ran very rough and powerless and I could tell before leaving the driveway there was a problem. Jannetty said to return the box for replacement. The truck runs smooth again without the box----but the engine light is on. From what I read this means a code was set by the faulty VA box. If so, is there a way to erase the code---- I know I can get the light to go out but is it loaded into the memory? My truck is an early 2004. Thanks, Bob
