It's not quite out of the box. It requires you to install EFILive and download your stock tune. You then email this to your vendor so that they can create a custom tune specifically for your truck. Once you get an email back from them with the modified tune you can then install it on your truck.Thanks for all the info. I didn't know you could dowload the software and do some pooking around without purchasing it. I had read that when you do purchase the product from a vendor they will linclude a tune or let you purchase one from them. It's nice to have something to go with straight out of the box. I tend to not leave anything alone. I don't think I would mess with a tune beacuse i'm flat out scared of ruinning my engine. I have also noticed that there are a lot of guys that choose to let people who know what they are doing tune their truck instead of the owner of the truck making tunes. That will be very helpfull to me in the begining untill I get a grasp on things. I think for now I will just read and try to find out all the info I can. I will remain a fly on the wall so to speak and learn from the pros. I'm not sure when I will purchase EFI Live but I will make a few phone calls when I'm ready. I'm not trying to waste people's time when I can find the info out myself. Thanks for your time and info.
Take you time in making a decision - in addition to downloading our software, download a couple of tunes from the tune library (both stock and modified) to see what other users are doing.
Cheers
