The Zippers T/max with autotune is a good unit that will allow you to use just about configuratin you want, Over the years it seems like they do have a relationship with D&D as per both websites , I have run the Rineharts TDs /with the T/MAX with and with out autotune in the past with no issues and base maps are plentyful ,if you go to the zippers website and take a look at there maps for your year bike and see what they have as far as basemaps, but with the autotune it doesnt really matter what setup you go with as far as air intake and exhaust, the autotune will eventuly tune it in , Basicly wih a base map it will tune in faster , the only down side to the zippers t/max for some people is that you loose the knock sensors,but it does give you the avalibilty to adjust your own timing ,witch I personly like.
