I have about 200 miles on my 06 Tib, now i know ur supposed to keep it under a certain speed and all that while u break it in, well i was in 3rd and i was goin fast but for some reason it felt like there was a power hold on it, as if the speed was actually slowing down as the rpms went up. I mean thats what it felt like..Possible could be the break in period? I also jus reset the Ecu by taking off the negative battery terminal. Possible could that have affected it? Thanks for your imput guys.
