I am just looking downtrack feeling the car pull and just shifting when it feels/sounds right. I guess thats why when I see someone ask........what should I shift my combo at...........I think that I would never have to ask that in any car as I just feel that as I wind out whatever I am driving I can tell when its time to shift. I think many racers probably feel the same. Believe me its not to try and sound like I am bragging but as many gearheads will say it just seems like I can tell pretty good about when its time to shift without looking at the tach. But of course I know a good racer shifting with a tach and shift lite will most likely be the most consisdent racer. Ron
