A 75 shot should be fine. I would definitely run the window switch and also a fuel pressure safety switch is a good idea. A purge kit is not a bad accessory to have as well.

ok thanks i bought the zex kit that comes with that computer thing that regulates the fuel supply so it doesnt lean out or run to rich and would it be ok to run it without the window switch?

Yeah you should be fine with a 75 shot, but pretty soon you'll increase the jet size. Then you will do it again. The "hit" is addictive but you get used to it and want more. I started of with a 75 shot on my 95 and now I'm up to 125.

At first on my 94 the S-Trim at 6 psi on the stock motor was enough. Now i'm at 15 psi with my T-Trim 383.

Boost and Juice are both very addictive!

You mean because you have a zex kit do you need the fuel pressure safety switch? Probably not, but that has nothing to do with a window switch. The idea of a window switch is to make sure that you dont spray over or under a certain rpm. If you think you never miss a gear or spray to early then you wont need a switch. I have a zex kit with a window switch and find myself flipping the switch on manually anyway lol. I usually wait to make sure im not spinning off the line and then switch it on. bkrep is certainly right though...lmao...I started with 100 shot and its only been a few weeks and im about to put the 125 in lol. The key is to not blow your motor, so as safe as you can be is the best way to go man...I had my kit installed for like a month but didnt use it because I wanted to get the window switch and the nos plugs first, but had to wait for end of the month checks. You better think about plugs to...your enemy is detonation, it only takes one time to kill an engine and they say that stock plugs are shot after one or two sprays and then det. could occur, get the zex plugs at least or iridium would be ok, platinum are no good for nos, platinum only has a 72 heat transfer j/m-sec.-deg compared to 147 for iridium and 401 for the zex nos plugs. and heat transfer is your friend if you dont want det. I know its hard to wait, but better safe then sorry.

Good luck and have fun
