4 tq is different in every gear, the amount of tq going to the wheels is going to be greater at the top of second gear than at peak tq in third gear even if the tq falls off 20 - 30 ft-lbs. thats just how power is translated to the ground through the transmission

That is, let's say we have Torque (T) and gear ratio (R) and we're shifting from 2nd to 3rd. When T2*R2=T3*R3, shift. If you shift too soon, you're giving up mechanical advantage of being in the lower gear (higher ratio).

2. You hit the rev limiter and must shift to continue to accelerate.


I have been wanting to mention all of those things especially the effect of gear ratio.


Back on topic.... Any news on a firm release date yet? And If we are on E85 will be be able to buy the larger pully and a base map with the stg1 kit?????
