Not good

Get a Nissan tech with a consult II to advance the timing 2 degrees. It did wonders!!!!! You must run Premium fuel but it solved my flat spot also reset fuel air mixtures

If your Titans run rich at WOT when you go into open loop.  Get a Adjustable Fuel Pressure Regulator, Adjustable from 30 to 75 psi. You will be able to adjust the fuel pressure down so at WOT you get 12.5:1. Your LTFT and STFT A/F in close loop will adjust to keep it at 14.7:1 for cruising. Mods will not change the way the LTFT and STFT A/F mix works in the ecu. The regulator return can T into the rubber hose from the gas fill to the tank. Start fuel pressure at 51 psi and with a Wide-band Air/Fuel Ratio Meter, drop the fuel pressure until you are up to 12.5:1 in WOT best to do this on a DYNO

Now all of us can adjust for any mods and better gas mileage and the price is right.

This will hold us over until a REAL PROGRAMER becomes available.
