I can tell you that based on the majority of the "information" in this thread there will be problems. There are many tricks of the trade and there are theories that work on paper and not on the street.
Nitrous is an oxidant not a fuel and if not properly designed and implemented will cause many issues and ultimately lead to engine failure. Small doses can be tolerated for some time no matter how improperly set up and I would advise starting small.
However a properly setup system has very little negatives and is very effective.

Gernby, you've inquired about the injectors and how much fuel they could support. Sice the D-4S injection is duel control it may be very challenging to find the fuel map (or even trace) for the direct injectors. I have access to the OEM scantool and I plan on making some logs of the OEM ecu to find this info out. However, the port injectors being 12V could easily be traced. But the ecu is setup to vary the fuel injection from both injectors based on various sensors and the programming of the engine ecu. So subing a large injector and making changes to the MAF signal will net you some undesirable results.
The other issue at hand is the ignition timing advance and how it is affected with the MAF signal. Heck even the ECT control is based on the MAF signal for a/t solenoid shift control so altering the MAF may result in erratic behavior of the transmission.

I really haven't done any research on the IS350 EMS but I can tell you that using the MAF tricks to richen the A/F on a nitrous setup generally never works as well as the age old wet kit. I believe I mentioned this before in our emails Greg. You will spend more time chasing your tail then it is worth.
No reason to even get into that on the smaller shots. When you already can use the piggy back to trigger the system and let off on shifts and so forth.
