Ok folks, here's my real complaint about the Sprint Booster. It's a decent attempt to fix the throttle lag which it does well. And I can't put any blame on the 1st gear ratio on the 6 speed, that's not the problem.
The problem I am experiencing is that the throttle is not linear when pressing the pedal. I don't have any realistic way to measure it, but it feels like within 1/2"-1" of pedal travel I'm getting power that I used to get at 80%-100% throttle. I just wanted to remove the lag.

I tried resetting the throttle, but it's still taking off too quickly in 1st. Now maybe I didn't do it correctly, so I will try disconnecting the battery over night and reconnect it in the morning. I'll see if this works but I doubt it.
