Wanting to get more low-end pull of of my otherwise stock Factory Edition. It's very smooth, but seems it could use a bit more snap off the bottom for clearing jumps right out of a corner, while keeping the top end pull it's known for. Any suggestions from the Forum? Could an ignition re-map accomplish this?
Gearing would help but you will lose some top end.
Try replacing the filter cage with 2 stroke screen cage and remove backfire screen.

Yes changing the idle will change the TPS. We had our meter hooked up and watched it go up and down as you twist the idle adjustment!
Waiting for the dealer to see why she will not stay running right now!!!
I also have the twisted vortex on my 19 450, HUGE improvement.
If you richen .02 Volts it will be richer across the range but less effect as butterfly opens more. Percentage increase will be less as you twist the throttle.
If you really want to do it correctly make sure butterfly is closed completely. Take filter out and look. That voltage is your baseline TPS setting.
