They most certainly work, and work well as most here have pointed out, however if as you say you are going to do future mods, you'd be better off getting most (if not all) proposed mods done and out of the way before you have a chip fitted.
This will save you having to re-map it each time and costing further money.
That's how I would do it anyhow.
