For the people who have some experience with ATX and tuning the shifts points, how did you do this to be optiomal? By optimal, I mean the shifts occur at the power peaks instead of reving high for nothing. I guess most of it is by feel? But what would you say are good RPM shift points for 1-2, 2-3, 3-4? I'll be playing around with it this weekend and just want some good base info to start with.

That will come more from how you drive , your mods , your likes then a "what works best"

OK, but from your experience in 1-2 where do you think the Duractec engine stops making acceleration? 6800RPM?

yeah, true that!
