Should I set it at 10 degree's or is there a different setting for more power and better performance? I saw some guys setting thiers 10 degrees off of the factory specs.

 

I have a 1988 F250 4 x 4 5.0 EFI and the timing should be set at 10 degrees BTDC. I have found people who run them at 12-14 degrees BTDC for a little more performance.

Actually, anything further advanced than 10 degrees would be for increasing fuel mileage. But then you run into the chance of causing your timing to 'ping' if you accelerate a little quickly. I have found the the factory spec is better overall for a good balance between power and fuel mileage. On my friends truck we opted in a 'performance chip' and it increased his power a fair bit and so far has not seemed to have sacrificed fuel mileage. Just a suggestion.
