Since Im running an svt I will only be going with a 50 shoot for now (yes a wet shoot) I want to invest in safety stuff before going too far, so my question is has anyone ran any dyno tune products the one I am looking at is at the top of this page http://www.dynotunenitrous.com/store/scripts/prodlist.asp?idcategory=44
Can anyone point me in the right direction because I dont really want to burn a valve, also j&s is too expensive for me at this point.

If your talking about the a/f ration lean cut off thing. That's un-necessary.
This will be saficient in cutting the nitrous if you start to run to lean.

You'll want a window switch, which will only let you spray at a certain rpm window. So you don't spray to early and your not spraying if you hit your rev limiter. If your using a zex I believe it'll already have a TPS WOT switch. Your going to need a tune to run your nitrous safely since you have a SVT. Check out this thread. Great info from Viney.

Sorry left that part out I was planing on running a window switch and yeah zex comes with one. I plan to get a progressive controller eventually. Part of the reason I am considering this is because it also has wideband so its kind of like two birds with one stone. I have a feeling its crap though.

Well, you could talk to SquillyB, or maybe he'll chime in................. .................. ....................... ................................ ................................ ...................... ............ ........... chirp ........ chirp ........ chirp ..................................., no, I guess not, but he was using a progressive controller and I believe it worked out rather good for him.

The J&S is cheaper then an engine !

You need a tune to lower the timing by 2 to 4 Deg , use a larger fuel jet 1 to 2 bigger then the kit calls for , use higher octane fuel 100+
