I would imagine you guys are running the OBD III. Not only did the forign market develope the computers, but its required in the US now too have them equipped. Very smart systems. Not for sure if your nissans are equipped like the hemi's, but i am sure they are. Best thing too do is love your truck, and dont waste cash on parts till there is a computer upgrade that allows them. Give the motor more air, and it will adjust too factory spec's. The computer will be way smarter then any Mod! Do you guys got electronic throttle?? If so your computer will be way smarter then any mod you will be able too buy. I explained this too the dodge guys, but they didnt listen very well. I work for dodge, so i kinda been told too leave my truck alone for a year or two. I would suggest the same for you guys. Here is a excerpt from some info on the hemi that may pertain too you guys also. This is only if your throttle is electronic, but it probably is. Article here if anyone wants too read it. http://www.popularhotrodding.com/tech/0403phr_hemi/ This is a small part only on the ECM, and intake part.

The end product proved capable of delivering cooler air than an aluminum manifold while only restricting the intake port 10 percent at full valve lift. That is about the same as a good aftermarket performance intake.

Unlike an LS6, which has a mass air system that allows the computer to adjust the fuel flow for any given airflow so that the mixture is always right (theoretically at least), the Hemi has a speed density system. This means that any increase in airflow into the engine goes unseen by the rest of the system. If a modification is done that increases mass airflow, such as a cold-air package, the computer has to be reprogrammed accordingly. Fortunately, two companies, Squier Inc and Street & Performance are working on this now and already have what is needed for transplants of the Hemi into other vehicles.

I wish i had more info for you guys, but through some experience i think you all should give your trucks about a year or two for the good stuff too come out. No use in upgrading if the computer is smarter then the upgrade. The titans are new as where the hemi's still are. let aftermarket learn alittle, and then play.. Wish you the best guys..
