well personally im all for the bottle. I ran the bottle when i had my V6 and it was def one of my better investments. Yeah its not like a s/c or turbo where the power is there all the time but meh it was even better surprising people.
I also used the bottle cause i used to street race alot when i had my 6-er and everything was hidden. I had the bottle for well over 200+ passes and nothing ever went wrong for me
Heres advise i can give you, make sure to invest into all the safety equipment such as a window switch and make sure you get thr right pills needed cause you NEVER EVER wanna be spraying when your car is shifting. Fuel cutoff switch, a heater blanket and a flipchip so you can switch inbetween NA and Nitrous. and most and very important is to have someone who knows about the V6 mustang
and let them tune it.
on the 99+ i found that a 100 shot can keep up with the fuel without changing anything in the system, a 150 shot your days will be numbered unless you were to upgrade the fuel.
Now for what i found the downside is the filling up on the tank this is why i invested into TWO 15 lb CF bottles i had the other stored away in a friends car. depending who your using it against you can get maybe if your lucky close to about 13-14 passes but theres alot of things that vary. cause in a reg 10 lb bottle i got about 8 runs in it.
Some people are ment to be nitrous junkies and then theres everyone else.
BTW if thats your car in the sig you def have one hawt looking car
