Steve,
I have a question.
You said that you were turning about 5,500 rpm at about 170 mph. Another member posted that they were turning a steady 5,800 rpms at an ecu limited 158 mph. How could you be running 12 mph faster and turning less rpm's? Have you changed to 20"s on the rear?


I checked to make sure Renntech took out my limiter, I ran it up to a little over 170 and it was still pulling hard. I had my eye's locked on the road, but I kept giving a quick glance at the speedometer & tach. I think I was taching around 5,500, I'd say she would do 190 to 200 since they raised my redline to 6,300 or 6,400.
