Nitrous? What the hell are you doing with your truck? lmfao

Is the N2O for you? If it is I find it ironic that you purchased it and your sig says, "There's no replacement for displacement"

Nitrous is not FI, it's a power adder.

If you have the source for that I'll eat my words. Otherwise, I stand by my original statement. N2O does not create increased air pressure in the cylinder.

I believe the NHRA does consider it FI since it is adding O2 to the system. Weird rule by my definition since I consider only super or turbo charging to be FI.

Types of Forced Induction - Advantages and Disadvantages
Turbocharger / Turbo / Snail * this raises the pressure of the air (boost) by using the exhaust gases exiting the engine to power a compressor that pressurizes the incoming air. Supercharger / Blower * this raises the pressure of the air (boost) by using the eccentric shaft / crankshaft to power a compressor that pressurizes the incoming air. Nitrous / Spray / Bottle * this raises the oxygen CONTENT or partial pressure by injecting nitrous oxide into the incoming air. A partial pressure of oxygen (pp O2) of .42 or 42% would be equal to the partial pressure of oxygen in air at 2 ATA, or roughly 14.7 PSI of boost. Oxygen at sea level is pp O2 = .21 or 21% of the total volume of air. Turbo Advantages: can be installed anywhere in the exhaust stream. Usually smaller than a supercharger. Uses energy that is already being wasted anyway; low parasitic loss. Modern turbos can be highly reliable and provide boost at a wide range of engine speeds (RPM). Modular, you can build or buy some or all the parts to make your own system or get a kit. Boost can be increased to the system without mechanical changes. Turbo Disadvantages: Can be difficult to install. Compressor is not linear meaning it does not provide a specific pressure at a certain RPM, may cause tuning difficulty. It is an obstruction in the exhaust stream lowering the flow of the exhaust gases and therefore lowering overall VE. Adds heat to the oil and or coolant (in order to cool the central housing of the turbo. Supercharger Advantages: Can provide pressurized air as soon as the engine is running. May also provide a linear increase in pressure due to it being tied to the engine RPM. Tuning may be easier than a turbo. Supercharger Disadvantages: Limited location area since it is physically powered by the eccentric / crankshaft of the engine. Uses some engine power to power compressor causing parasitic loss. Typically not modular. Boost cannot be increased without mechanical changes (smaller pulley). Nitrous Oxide Advantages: Inexpensive to purchase and easy to install. Does not cause any additional heat of the intake air (intake charge). Can be installed in numerous locations depending on the size of the bottle. Easier to maintain. Nitrous Oxide Disadvantages: Must refill bottle. Typically only on during wide open throttle and or a button is pushed. To reach any significant power levels, some expense must be added for engine management. Special note about temperature and air: when air is compressed regardless of how, it creates heat due to the friction of the air molecules being squished together. Intercoolers and other modifications have been invented to cool this charge air, but the reality is that 1 cubic foot of air compressed into 1/2 cubic foot area will become hotter, thus is the nature of gas. So both a supercharger and a turbo will create more heat than a naturally aspirated engine of the same size and design. This does not account for heating of the exhaust gas due higher fuel volume in the chamber, all FI will cause a hotter “burn”, this is a good thing when properly managed.
