I've read some other posts about the Dobeck tuner, and I'm trying to decide about adding one. All stock 103ci, no exhaust mods. Some of you will recall I was having pinging issues and the dealer sent my ECM back to HD to get reset. It has helped, but I still get a ping now and then. 1) Will adding something like a Dobeck help, or do I need to change a bunch of other stuff too? 2) Will I be able to handle installing it myself? I am capable of doing oil changes and basic stuff, although lately due to time constraints I just let the dealer do that stuff too. I hate the thought of causing more problems... I'm not much into tinkering with the bike, I just want to ride it and not mess with it other than basic service.
