THis is by far the best upgrade that I have made to gain power in my STI. It is super easy to install. I've had mine since Feb of 2007 and have done all of the firmware updates to inlude the addition of the performance timers. The new maps seem to be more fuel efficient and with the addition of the launch control makes driving the STI even more fun. A must have!!!!!
