My check engine light is on now too. I guess I will have to bite the bullet and buy one. Anyone have a used one for sale?

You most likely threw a code cause you installed the cold air intake. That's why I was curious in the first place why the stock airbox was on and the Cai in the trunk.. As well as your speedo being off. Your putting a lot of extra miles on the car your not driving!! Call Brenspeed tomorrow and have a tuner shipped with the tune in it. Plug it in and add a lot of HP as well as solving all the problems together in one shot. It "needs" to be done at this point
