Nitrous and Tuners?

I ordered a complete NX kit and will be installing it in my car. I have a diablo tuner and can probably get a custom tune emailed to me but I was wondering do I need a chip to have multiple tunes or can the Nitrous tune be used as my daily driver tune aswell. The NX will be turned off at all times unless i go to the track. I saw the SCT eliminator 4 bank chip, which it looks good but is it necessary.
 
SCT Livewire and Predator are nothing alike at all. They feature some of the same options - but the interface of the Livewire is currently totally proprietary and unique to that platform. You can't use a Predator to datalog like the SCT and you can't use your Predator to get readouts (ie: functioning as a dash mounted gauge pod) for 6 different metrics. Your Predator doesn't do dyno estimates, nor does it do 0-60 clocks, or 1/4 miles clocks with a built in starting tree. Totally different. Only similarities are that it plugs into the same port and has some of the same tunability options.

what i meant is they are the same as in all i need it for is to get a tune emailed to me, plug it to my car and program my car. I don't need all the other features for that (i think)
