You can not use the dead time specs on that site for your Accel injectors. The data on the web site is for Accel high flow injectors which are low Z. Low Z injectors open much quicker than high Z injectors such as yours. I would use the settings shown in TS to get started. This is for operating the injector @13.2 VDC and at a fuel pressure of 43.5 PSI. The voltage correction of .200 ms/V adds ms time for voltages lower than 13.2 VDC and subtracts ms for voltages above 13.2 VDC. The values are interpolated by the MS code when it calculates the desired injector PW for each injection event. If you run your fuel system at a different pressure, this also affects the injector opening time. But you have find this information or buy high end injectors where this information is provided. Higher pressure slows injector opening, and lower pressure will decrease the opening time.

What boost pressure are you running? You will probably need a little bigger injector.
