Two reasons, money and knowledge. The price difference between V1 and V2 is about the money I needed for my wideband. I just dumped another $800 last night on gauges and mounts. I'm just trying to save where I can. I will probably never unlock all of the features of V1.The DSP5 switch's are only for diesels.Gotchya I am pretty sure that is for version 2 only. I am in the process of ordering it right now. It will allow me to have an economy tune, 2 different towing tunes, a hot tune that I am running right now an a extremely hot tune. I am tired of uploading between tunes.![]()
J-Rod-And why not go with the V2. Since you are pre 07 you don't need it but there are lotsa sweet features with the V2![]()
