[66shortwide]

Hey guys,
Was thinking of going ahead and buying HP tuners - everything I've read indicates to go ahead and get the pro version. Anybody on here use it? I've got my 4.8 in my 66 truck I'd like to tune on, and I would also like to use it on my wife's 2012 cts-v. I saw a lot of talk about wideband sensors - so do you have to install one on every car that gets tuned?

Lots of questions, just seeing if their is anyone with some experience with it.
