Hi Guy's. Im just waiting for the rest of my parts to do the stage 1 upgrade. The dealer has warned me twice not to forget to get the dealer download. The info that came with the filter and pipes warns you to do the same. I realize from this forum that the download only takes the system back to factory lean. I am installing the TFI from Doebeck. My question is this. If you can cause serious damage to the engine without the dealer download what if the TFI goes bad and your no where near a dealer. You may have to run the bike for an extended period of time without download or your TFI. Would it not make sense to have both installed or is the TFI only suggestion, just for cost saving. I'd sure hate to hurt my baby.
