tuning your own computer

[bark]

Hello, working on my 6.0L swap, and I started thinking, would it be worth buying the soft ware to tune my own computer, that way I could have a tune specially for my set up, and be able to change it if I decide to alter it in any way. I also drive other gm trucks, so would be able to tune them? I just did some quick reading on HPTuners, and also EFILive. HPTuners mentioned about credits, I assume this is how many times you are allowed to use there product, not sure if it is for different vehicles, or every time you plug into the vehicle?

I know I may be opening a can of worms, and it would probably be better just to pay some one that has experience doing to do it, (which is probably what I will end up doing in the end) but its just an idea

Has anybody elso though of this, or has anyone done it, not that I wanna be all fast and furios by having a laptop sitting on my consoul and tuning air fuel ratio and timing every time I drive... I just though it might be some thing to consider, especially if changes with cam, intake or exhaust are going to happen

any info or tips would be appreciated
