Default GT Tuned - Need to Change Plugs?

Well, American Muscle sent my dad the correct tune and it's ***** to the wall now.

We can't believe the difference that it made.

I know that we should get Bren or Bama to send us a tune, but what we have for now will do.

We were wondering if it is necessary to change to a different heat range plug?

05 Mustang Gt - 5 speed, JLT Cold air intake, SCT 93 tune from American Muscle, Pypes offroad x pipe and Pypes Violator axle back.

Thanks!

No, you only need to change plug temps if you run nitrous, a turbo, or a supercharger.
