Gained 10hp mid-range.
Lost 5hp up top.

Other people are getting same results I did with EMS.

No dyno sheets to post as the PC used was not saving them properly.

So overall, what does this mean? Is this header worth it? I just bought one, so I am hoping the answer is yes. Am I right to say that with the EMS the ecu doesnt have to re-callibrate cause there realy is no more ecu? I hate to lose any power in any range. Is it better to have more mid-range or up top?

If you are running an EMS you should retune for any changes.

Whether or not the header is worth it will depend on a lot of things, including what you use the car for. Midrange power rocks for autocrossing and track use, but the loss of power up top sucks for drag racing, depends on where peak power was moved to and so on as well..

If we had the dyno sheet we could get an idea for what the curve looked like.
