No worries mate. Like what Sarah said above, the Superchips stuff is made to be used on an otherwise standard car and so if you're engine is anything other than standard then it won't be doing much at all. It's also going to put the same data onto every car of type, so it'll map every 197 the same for example, but these engines are not all made equal as many have found out on here (some are underpowered, some are overachievers) and because of that it's impossible for them to say it'll give you x amount of BHP. There's no way of them knowing that your car is the same as the one they developed the map on.
