You cannot solve drive by wire delay with a piggy back solution.
What you're doing is simply forcing your throttle modulation more at a given pedal position. In other words, if you're pressing the gas pedal with a force of.. let's say 1 newton. The system simply tricks the ECU that you're pressing the gas pedal with 1.5N of force. Simply put,
pressing the gas more will yield the same benefit in a non-Sprint Boosted vehicle.
In other words, you're paying more just for you to feel power that all you need to get is press on the gas a tiny bit wee harder. If I'll be frank, you just got scammed.
Don't wanna believe it?
I'll bet you a dyno-run that your overall power figures doesn't really deviate from the norm. If I win, give me a free Dyno run and pay for yours, if not, you get to have a free dyno sheet
It's just how Toyota tunes their Vioses and Innovas. They aren't made for great handling or good response. They'll give you a response that
optimizes fuel consumption so consumers won't complain that getting from Point A to Point B takes too much gas.
Tignan mo yun Mazda3.. great response and handling pero mga tao grabe umangal sa fuel consumption.
