Here is an ECUtek data log for a full throttle pull through 3rd gear on my stock 370z 7AT.

The injector duty cycle at about 7300 rpm shows at 86% which is about correct for the indicated injector pulse width of 14.12 msec. in 16.4 msec for 2 engine revolutions. If the engine power is increased with boltons by about 30 hp it would seem that is near the limit for the stock injectors unless a/f ratio is leaned out. Mine is currently set at a conservative ~12.0.
