No, thats just a guess . I tried it and through codes . I thought they cleared themselves out when the check engine light went off , but they did not . I went to the dealer today and had them cleared .

 

Back to the top speed eliminater. Yesterday i opened her up to 108, and the speed limiter kicked in which was 3000 rpm. So i did the key trick, and turned off the speed odometer. When i did that it ran to 3300 rpm which was 115 mph when i turned the speed o back on. In the earlier post some stated that the ecm defuels at 3300. That appears to be right. The top speed eliminater doesnt raise rpm on 04.5s just fools speed limiter. So it looks like will have to wait a little bit longer.
