some one told me that it goes before the meter and when the nitrous blow past the meter is automaticly adds more fule cause the meter reads the extra amout of nitrous and the computer thinks it is air

 

Im not sure about that 5.0mustang but, remeber one thing, if you go with a N20 system then make sure you look into Flip Chips. Where you can get by without a tune on an S/C, you cant avoid it on the juice. How your vehicle will handle the magic stuff all depends on how well tuned your car is.

 

Couldn't have said it beteter myself! I think I am going to go with the Malory ignition setup which includes the window switch and even first gear lockout if I am not mistaken. That way, the timing will automatically be adjusted eo whatever I set it to as soon as the nitrous is engaged. Then it will return to normal when off the jug. You could always buy a timing retard from MSD, but then you have to remember to retard it on the spray and advance it back when your n/a.

5.0, I believe that most of those kits are for imports. You can get one of those Zex filters that has a boss in the front to thread the nozzle into. I wouldn't recommend doing it that way though. Place the nozzle between the TB and MAF.
