Re: Nice Picture

Anyone know?
What would you speculate the top speed would be then?

At the track I would hit 130mph indicated on my speedo. At the same time howerver, my nagivation unit was reading at about 125mph. I have found that my sti is roughly 3-5mph high verses what I am actuallying doing.

It seems like the speed limiter would run off the speedometer because if the ECU could limit speed through a more accurate way, well then why dosent our speedo utilize it?
