hummmm....i read the description and it states below:
"Boost Mode:
Throttle response time will become quicker and results in improved accelerator pedal feel.
Returns to normal mode once pedal is pressed to fully open throttle."
why does it have to return to normal mode after wot?
that i was the deal breaker for me...
primary purpose for me is to reduce throttle lag. i dont care about fuel economy on my Z.
