It should make it a little more eager but it's all relative. Let's say it frees up a handful of horses, you're not going to notice much change when you're pushing well over 200 already. It's the sort of thing that I'd only change when the OEM one needs changing anyway, say after its first 3 years.
If you're hunting performance then a remap, alongside a new exhaust and filter, will probably free up about 50-80 horsepower for a grand or so. Anything more than that and you're looking at megabucks for new engine internals and a bigger turbo.
