two questions.... (and don't laugh because I don't know much and these might be really dumb questions)
1 - my exhaust looks real black at the tailpipe and someone seen that and told me "it is running rich so don't worry about the tune" , is the black tailpipe a true sign it is running rich ???
2 - I told someone I was thinking about running the car on a dyno to check the tune and maybe change the pulley and he said "if you are going to re tune it you should switch to e85 and tune the car to run on e85" is setting it up to run on e85 better ???

Yes black exhaust is usually an indication of it running rich. That sometimes isn't necessarily a good thing, depending on how rich its running. Still its nto the greatest advice to give someone. I would have the AFR checked, and retuned if needed.
Switching to E85 will require you to spend a good amount of money. If your looking to get more power out of the car, E85 is a great way to do it. However there is no real reason based on your previous threads, for someone who is thinking of changing pulleys, to get less power, switching to E85 is going in the opposite direction.
