Evo has three settings and you can control the curve. if it was mine would think about an intercooler but wife just said yes to the box. would love to have one running on 40D one day!

Ive got a different kind of
chip on my wife's 40d, but it's pretty useless. The ECU seems to cut out on hard acceleration.
Searched the forums, others have the same problem.
Good to hear that you have no issues.
