In my opinion, the Evo intake was a big improvement without the computer mod. Definately try to get the exhaust done as well. I did my B and B exhaust and Evo mod in the same week and it was a huge improvement. Cant comment on the computer upgrade.. I have yet to do it.

You will love the intake sound from the Evo... it is worth the price even if there were no noticable gains in HP.

I wish you would do the intake first and the the computer mod to see if there is much difference with and without the computer.

Good luck!
