Need some Dyno expertise. I am used to manuals and this is my first time dynoing an automatic. Because of the 95 mph limiter on the truck (due to the weak drive shaft and probably the tire speed rating), the dyno tech said that the stock truck won't hold 4th so he is forced to do a 1st through 3rd pull. He will then do the same thing after my modding and tuning so I can see how much more power is made (this was a baseline tune). Because of this, the dyno was graphed vs MPH instead of RPMs and I am not sure how to calculate my actual HP because of the gearing (I believe for the 6L80 the gearing is as follows: First: 4.03. Second: 2.36. Third: 1.53. Fourth: 1.15. with 4th being the closest to a 1:1?). Is there an accurate way to pull out the actual power numbers from the MPH graph since it is graphed vs MPH instead of RPM (65 to 95) while accounting for the transmission gearing and rear? The Dyno Graph is attached. Thanks for the help!
