Ok so I have an s13 and what I do not understand is that stock speedometer goes only up to 115... and I have a auto (SOON TO BE 5-speed <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt='

'> ) anyways I got it up to 125 or so I think... and that is where it max-ed out... there was a limiter so yeah that is my two cents. I did this for about 10 mins also… <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>??
