According to the makers of the Sprint Booster, in ten minutes you can halve the throttle response time at low revs if your car has drive-by-wire. They don't say exactly how it does it, except to reveal that once you've plugged the gadget in, it monitors the signal from the accelerator and provides the ECM "with a new and altered signal." Mid-range acceleration lag is said to drop to "almost zero."
The device will fit Audi, BMW, Mercedes, and VW, among other cars. Sold in England, it's claimed not to affect your insurance or MOT, but it doesn't say anything about your manufacturer warranty. Although with a 10-minute install time, it shouldn't be the least bit difficult to remove if necessary. If those milliseconds you've been losing at stop lights have really been eating at you, the surge you need will run you $330 plus tax.
