Whos done it for $99 I wouldn't mind water and intake temp, Im not sure about the boost and air fuel upgrade I haven't had any boost gage issues in the past and the air fuel is the same Bosh probe that I have had connected to the AEM display. I have replaced the air fuel probe a bunch of times in the past so the same probe connected to a different display shouldn't last any longer. Any one have any thoughts/ experience with the reflash and the upgrade.
