Plugged one into my +02 Ram 5.9 4x4 & it read I did not have the standard program in the computer !!! I bought & imported this from the US to the UK. The question is, how do I know what setting I might have in there at the moment ? Its not that peppy to say the least compared to my obviously lighter 5.9 Jeep Grand Cherokee but if it were in say the towing mode would that dull the performance off that much ? I will be getting it sent off for a B&G flash once the final mods (headers & 1.7 RRs) have been installed hopefully in the next couple of weeks.
