i dont think your JMS tune did much to affect your timing. you will need to run richer when you spray. so, your options most likly area Timing adjuster, and retard the timing, and hope it works well...or do what i consider to be right, and get a tune done for your car while its on the spray. performance wise you will be better off, and you also will be safer. theres no real reason to skimp out on this, as the cost of a tune will far offset the cost of a blown engine.

p.s. if i had spray, and a f-body came up next to me and wanted to roll, i would have to open the bottle and spray his a^^. but only if it was deserted and open.

14.6 geez your in NPI territory lol. My best last week was a 14.50@94 w/a 2.1 60ft and the 2.1 60ft was w/18'' saleen replica's lol. Your gonna need juice just to run with your own PI guys. Good luck, oh yah and get the car dyno tuned on the juice.
Alright, well here's my current situation with possibilties.
I have just paid my car off today (thank god) so basically I can do whatever I please with it.
Now, I was thinking at first for some quick HP (Juice), but I was also thinking down the line. Now, my other option is to save up for a blower, maybe KB? Vortech?
In all honesty what would you guys do? Save up for the blower + install or slap on the juice?
My car - 03 GT with roughly 4K miles on it... I don't drive it in the winter around here... will a KB or Vortech kill my internals? If I go blower I want to have everything else stock for the most part if I can as far as internals go. And I want them to last. What do you guys think?

Alright, ditch the chip or get a re-tune. It undoubtably bumps the timing up a few degrees which on a sprayed car will destroy the engine.
You will need either another chip or a timing adjuster to run a 100 shot. Some say that you can run a 100 w/o bumping down the timing, but I know of one person (the guy a MD.com w/ the 98) who destroyed his shortblock w/ a 100 shot and stock timing.
For the whole kit plus the bottle heater, which you really need if the pressure is too low you wont make as much power and will run stupid rich (me). Also look into a window switch that activates the nitrous at a predetermined rpm range, 3000rpms on and shut off at 6000 rpms is ideal.
Get the NX kit, it's the best out there with the best solinoids (comparing to NOS and ZEX, I know little about TNT or Proflow).
If you can get a flip chip so you can have a n/a tune and a nitrous tune that bumps timing down 2 degrees (this way you can run up to a 125 shot, safer is better than sorry). Also moving your shift points from 5500 to 6000 on the spray will help ALOT. My car is shifting at 5500 and it is just killing my times.
Here's a graph of my car with the mods in sig and a 75 shot. Due to my lack of bottle pressure (800 psi) I was WAY rich and only gained 65 horsepower and 100 lbs. Not bad for only $500. If someone says a supercharger will be cheaper in the end they are just plaing stupid. It would take about 300 bottle plus or minus to equal the price of a blower, that's a damn lot of nitrous. I go to the track 3-4 times a month and have had my kit since March, still on my 2nd bottle w/ 75 shot.
An auto is ideal for nitrous, no missed shifts, no having to powershift.
As a last note, w/o a shift kit or bumping the line pressure you might hit the rev limiter when your car shifts. The tranny takes a set amount of time to shift, but it starts the shift at the same place with or w/o alot more horsepower. With the spray your car will naturally be accelerating faster so the car expects shifting at 5000 rpms will result in a shift at 5500, but will end up much later as it took longer to execute the shift.
With a 75 shot my car gained 8 mph and 7 tenths. I'll be going to a 100 shot with good bottle pressure later in the summer and get the full gain.
If you have any questions/concerns feel free to ask. Nitrous used properly is no more dangerous than driving a blown car or a n/a car for that matter. Sorry if I answered and questions you already knew, I'm not sure of your knowledge of nitrous.
Good luck.

Red35th, what gear do you hit nitrous in? I dont really know jack about nitrous, so sorry if it sounds noobish. lol. I was thinking maybe not 1st, because with high rear gears and a powerful N/A motor, 1st is pretty non-existant and goes by fast enough... Furthermore, you wouldn't want your tires to break loose... But I dont know. hehe
