I have read many reports of horse power and torque increase after a few thousand miles of use . Is this fact or fiction? Any testing or dyno reports to verify?? I have 03 short track with approx 700 miles on. (recent purchase)

Difference
To be honest, I couldn't ell any difference at all. I always wonder how others can. Even if you gain 5 to 8 hp, I don't think that is enough to notice without a dyno. How many cars have you bought new that seemed more powerful after breakin? I had 1700+ miles before the Turbo. Now that is a noticeable difference!

With 2400 miles on my 03 I didn't notice any real change in performance. I think it's hard to feel a 2 or 3 HP increase over a thousand miles.
