I have the Acessport on my STi and its a great product, the gains were large and the powerband is alot more constant right out of the box with the cobb maps. I wish I had found a deal like the one here though as a cusom map would be nice without paying the price for tunning. They do software updates pretty regularly that are easy to install. Also yes you can get rid of CEL with midpipe and your car will pass emissions too if you need to.
