It's not throttle lag. Drive by wire systems will open at an optimum rate. Mashing the peddle doesn't make the motor rev as quickly as a throttle that opens at the same rate that fuel and spark raise.
These things are gimmicks, no better than the air intake temp sensor box. Yes they will make the throttle open more than where your peddle actually sits, but they don't make any more power. Does it matter that you reach 100% throttle when your peddle is only down 75%?
You need to do something to the ECU to change the way the throttle opens and if it gets WOT at low RPMs. Forcing the plate open to 100% at low RPM with something like these devices doesn't change the fuel or spark down low, so the ECU freaks out and does weird things. You have to adjust the parameters in the ECU to take advantage of it.
You're better off just slapping a bunch of neon lights and stickers to your car.
