Standard TPS setting is .54 volts with key on (car not running) and 4.49 volts with accelerator pedal fully to the floor (WOT). You have to play with the setting a little to get both idle and WOT setting.

So of us that run modified engines have discovered that a idle setting of around .60 get us off the line a little faster with better response.
