Further that with the torque curves seen in just about every dyno map done on a stock 370z, with a huge dip between 2500 and 3000 RPM, and the hesitation makes perfect sense - not that it does not suck.
It is ironic that a simple fix such as the gadget that increases voltage to the gas peddle is all that is needed to overcome some of the hesitation, but the inherent design of the engine and mappings make it fairly difficult (or at least some serious investments) to overcome.

Agreed, there is an inherent lack of response... but again, there is a change in the car. It gets REALLY bad after some period of driving. I find that in-city driving make it much worse. I lose SO MUCH power that I feel like I will stall if I release below 1500RPM. But not all the time.
