Is there anything out there I can use to be able to switch between two different tunes? I plan on running a nice, mild H/C setup with a TNT wet kit on top........and I don't want to sacrifice performance AND safety in either case.

All you need is a timing retard box, if they make one for ls1's, Change the N/A A/F a tad richer and use a wideband to get you A/F correct on spray and adjust with the fuel jets....

The LS1 Timing Tuner will allow you to run your full timing NA and then pull some when you spray. Here's a link:

Or if you have HPtuners, you can setup a NA tune, then have a TNT tune. (pulled timing) then just load one or the other depending on which one you want at the moment. Thats what I do.

Have you had any experience with EFI Live? I was leaning towards HPT because that's all I've heard about.......seems that just as many people like EFI Live.

I have live and it rocks. In the near future you will be able to do what you are wanting without a box or other hardware, its all in the tune.
