I got my car to a little over the 150 pic and I also have a white sedan automatic, but no chip, only intake and 2.5 exhaust. The needle was at the "M" in mph on the bottom and that was about the time I hit my revlimit. I wasnt exactly staring at the guages if you know what I mean. I was actually following a 95 M3 but couldnt quite catch him. He had a 5 spd. I was only a couple cars behind on an open road here in texas

with three wide-ass lanes and straightaways for miles and miles. I love texas. Thats why our speed limits are 80 in some parts, like that matters.
