What are your rpms at 65-70 because I was thinking about doing the same. Did you have an improvement in that range. It makes me mad because 45-55 I get 18+, same for 75-85. But I get 16 at 60-70 and guess what speed I'm supposed to be driving over here?
On the two manuals just keep in mind that the gryphon has options/improved options compared to the edge evo like the datalogging.
