Boost Controller for 2003 Audi A4 1.8t for power gains?

I wanted to boost the overall power my car. I was going to buy a supercharger(well it's not really a supercharger) for around 5-600 dollars, but this only gives a 10hp gain at best. I heard that I can re-program the stock turbocharger in my car and get much more significant gains for around the same price. I was just wondering whether or not this is true and whether I'd do this using a boost controller or would I use a different device? Links would be helpful though not necessary.
Thanks
