think baby needs a bottle

another thing you can do is run a window switch, it will turn the solenoids on from rpm ranges that you set.

Adjustable timing and a seperate fuel system for nitrous is a good idea.
Fuel pressure cut off switch are nice but I have had problems with them before reading right.
Two big things dont get greedy and stay off the button as much as you can. IE no playing on the street for more than 10-15 seconds at a time.

stock bottom ends can usually handle 150 hp all day but go with a 100 shot to be safe.

Air fuel meters are also nice to have and strongly recommended when doing nitrous, if you go lean it will cost you. oh and not some cheap autometer narrow band crap one..get a good wide band. It will cost you 300+ for the meter.

To run nitrous right plan on spending 1500.00 for everything.

I have run nitrous for 5 years on my dak and will run it on my dart some day.
