Much thanks. Will be looking forward to seeing the numbers tomorrow. My 2010 is 2080 at 70 mph & think about 300 hundred more would have been a lot better. New 5 speed with the OD being lower geared should create significant higher rpm with the same 410 gearing. Thinking the sweet spot should be around 2400 at 70 mph, so the reason for the request of both the 373 & 410. The 2400 at 70 perhaps is not the sweet spot, so if not why?
