Do we have to go through burning off that so called chip in the 05 mapping that's reinstalled now. I ran mine right after having the 05 mapping put back in and can only see 117 on the speedo. I was seeing in the low 120's with the 06 mapping. This is runs in the 2000 foot range. I did have to knock my clickers down, because it was reving to 8000. I could sure notice the difference in idling and taking off how much richer it is. I bought it used, so I really didn't get to feel the initial break in feel.
