Nitro
Any one out there have some experience with nitrous on there 5.4? I have a 102k 2002 F150 FX4. Alll highway, but obviously not brand new, but I wouldn't say worn out. I put on new double plat. plugs, fuel filter, K&N intake, flowmaster 3" exhaust and feel ready for a 100 hp nozzle nitro. It seems that a few I have spoken with think that up to 150 hp would be ok but from some articles I have read over 35% more than stock and you need to change some other parts. I was looking at the NOS system that only engages at full throttle and shuts off if you let off the gas at all. Any body have experience with this system or a similar one? Or is this all to risky for my daily driver?

I was also thinking of running fresh 87 oct with cans of oct boost on the weekends that I go to the dunes, what to you think?

It's up to you. Before you go dunin', run a test on the street and listen closely for any detonation, and make sure you have 93 octane for a 100 shot. 90 will work, if half the tank is 87 and half 93, but you'll be askin for detonation on a 100 shot with 87 octane and plat plugs. But definitely do a test before you get triggerhappy on that nitrous 
. I wouldn't worry about it too much, just take precautions like shellin out a little extra cash for 93, because it would be a lot cheaper than repairs should something go wrong. Hook up that bottle and have fun!

I feel stupid but I thought that the premium at the pump was 93 but I found out that it is 91. so all this time I meant 91. Sounds like 91 is the ticket, i wonder if 91 plus a can of boost is better or a waste or worse?

A can of octane booster, if you read it completely, will give you about 3 points. This is equil to about .3 octane, so it would take many, many cans to get you up to 93. I would fill the tank with the premium (91 or 93 depending on area) a week before you go playing with the spray, this way you will have true 9? octane in the tanke to keep the detonation away.

Forget using that octane boost stuff to increase your octane level. Go find the local speed shop or gas station that sells to the hi-performance crowd and pick up a few gallons of high octane. The local shop here has 104 unleaded (114 leaded).
4gl @ 104 = 416
21gl @ 91 =1911
416 + 1911 = 2327(total octane in 25 gal. tank)
2327/25 = 93.08 octane rating
This way you'll know what's in the tank. The other way your just guessing. Read the side of the octane boost cans and they say stuff like "treats up to 21 gallons"
The drawback is the $6.75 a gallon for the 104(5.95/gl for unleaded) however if it's just a once in a while thing the fun factor of the higher octane will far outway the cost of a few gallons.
Try it- you'll like it.
