which tuning software?

I already tried to search but i am still unse=ure what i need to get. I am pretty sure i want LT1 edit or tunercat (JET). My mods are in my sig, i just really want to get it tuned better and want the best software for the money. Does one have more tuning options? And what is the easiest to use?
Any help is greatly appreciated

Thanks Scott

Although I have (and am preparing to use) LT1Edit, I have heard that TunerCat is superior. Just my two cents worth.

I am curious about this too.. I had mine tuned by pcm for less and it just doesnt seem right my idle is funny along with getting numerious codes. I am wondering with these programs can I save the previous pcm settings to the computer before overriding them?
