Don't need a tuner, just curious what my car is putting down in situations like this. I know I've lost some power just don't know how much.
The problem with dyno pulls to check subtle things is that you really need to be on the same dyno under similar atmospheric conditions from your baseline. What you perceive as a difference may only really be 10HP on the top end, and dynos can easily be that far off from one another. Another way to check is if you have a base of timeslips from a given track that is consistent AND you are a consistent diver (i.e., not Sean). If your mph is off by more than 2mph on average, you are definitely down on power.
