The Grimmspeed one comes to mind. If you have a datalogger you can compare commanded AFR to actual AFR to get an idea of how far off the scaling is.

The CAI was recommended to me by someone who had one. This is the first car I purchased on my own that has more than 130HP (lol). so i'm pretty stoked about adding stuff to it. maybe I jumped the gun to quickly haha. the car has only about 4000 miles on it
