OK, blublyu2 is all this talk directed at me? This thread is about dyno,s and bagger,s. I posted my runs on the dyno. The chassis dyno is power to the ground correct? The dyno at Bennetts is a chassis dyno not an engine dyno.I,m not hating I,m simply stating my numbers as they are and what I did to my motor. My first map in the thunder max was based on my build and a program that thundermax sent me. Since then they have made some adjustments to the maps a couple times based on me sending them my info from my thundermax them tweaking them and me reloading the program. I agree that having someone knowledgeable with the thundermax and a dyno for fine tuning would be ultimate. Eric doesn,t no the thundermax and the specifics of tweaking it. He does no the power commander and how to get the most from it.He simply stated that with the pcIII and very simular builds to mine he always see,s better number,s with the pc,s.over the thundermax,s. Like I said my bike runs very well does great burnouts and the powercurve shows on the dyno that it pulls very well from 2800rpm,s write on thru to redline. I,m simply trying to get the most out of the build.
