Thanks Shelby ...you've got a good-lookin' Saleen, something I'd like to have (but can't afford)
Scrapla... I agree w/ exgmguy... you don't have to rush out and buy an MSD box, etc. ...but it never hurts to have one
...just be sure to, at the very least, run fresh plugs, wires, cap, rotor, fuel filter, etc. if you haven't changed 'em in awhile. A tune-up in other words... there are a very large selection of add-on accessories available to make your nitrous system work to it best ability, some you can get by without. It ultimately depends on your budget and what you have planned for the future, right?
