I did it just the other day along with using throttle body cleaner and cleaning the MAF sensor (don't worry, I used the right chemicals for that).
Take off is improved. Don't expect to be able to launch off the line, though. I will say that you'll notice the largest difference when you have it floored. I noticed the biggest improvements at 3,000+ RPMs. Once it hits 3k it flies.
Although my gas mileage has dropped with it
