I recently purchased a 98 GS 400 w/ 80k on it. Last night I was curious to see how it launched off the line. I had it in power mode w/ the traction control off and I was expecting that if I floored it that the tires would break loose which they did'nt. I then tried putting it in L (1st gear) and still nothing. Then I tried to power break it and the wheels only spun a little. But dont get me wrong it still put me back in my seat. I also tried resetting the ecu before I tested it. I was just wondering if anyone had any suggestions to what was wrong or if other people experience the same thing? Its just that I remeber when I was with my buddy in his GS400 he broke the tires loose like it was nothing.
