my own bottle cap Sprint Booster
Well after doing a little bit of research on what Sprint Booster does I have came up with my own no cost design to help with lag and increase throttle response.
Get a 2 liter cola plastic bottle cap,( fits perfect for what we need), some scotch tape. Tape the cap directly unto the kick down button under the gas pedal.
Since throttle is controlled not by wire but electronically you must do the transmission reset so when the kick down is pressed throttle signal will read at 100% ( verified by an obd 2 reader)
Now the ecu readjusts the gas pedal range so 100% throttle is closer than before and whalla, my own sprint booster
results: less lag, more aggressive throttle
Don't believe me?
try it yourself and post back the results..

why in the world would you want to have the kickdown pedal depressed with a light foot? its only good for serious passing or serious acceleration otherwise its gonna be just jerky, don't knock the sprint booster untill you try it 
this thing is no joke

lol then you are not too bright , why in the world would you want to have the kickdown pedal depressed with a light foot? its only good for serious passing or serious acceleration otherwise its gonna be just jerky, don't knock the sprint booster untill you try it this thing is no joke

Car is not jerky at all and I'm not knocking the spring booster, its just an experiment here but I think it actually works
thats why I want someone else to try this

hrmm wait so its only a bottle cap? I misread your first post lmao, I thought you taped on a bottle inbetween the pedal and would of had the kickdown hit every time you gas it 
just a cap seems ok i guess

kick button engages 1" sooner and looks like range of the gas pedal got decreased by looking at my obd2 computer. 100% throttle as soon as the button is pressed even though gas pedal does not go as far down as it did before.

Having just replaced my throttle position sensor and relearned the ECU, I am inclined to believe this will behave very similarly to a sprint booster. The only real possible difference is this remaps your throttle linearly (effectively just decreases throttle range and increases throttle sensitivity), whereas the sprint booster, at least in theory, could apply a non-linear mapping (although I highly doubt it does).
Maybe someone with a Sprint booster can disconnect it and try this to confirm if it works similarly or exactly the same.

Im thinking about it, and there is no way this can work like the Sprintbooster, ok you have a bottle cap on the kickdown, but that means you will have to hit the kickdown atleast a good few times a day for the ecu to remember the settings, and living in a city kicking down is not really an option on the streets, the SB works as soon as you touch the pedal and never forgets its settings. All this said we are assuming the ECU even recalibrates the pedal range which I doubt it does in the first place, so im pretty sure this whole idea is BS, the only benefit is you will hit the kickdown earlier, with no effects in the pedal range before that.

The stock electronic throttle appears to be able to recalibrate itself. This is different from cable based throttles. If anyone with a Sprint booster wants to test it, I would once again suggest comparing.

Sprint booster...almost NO lag at all..
