Hi, I have suddenly noticed from getting a top speed of 105mph on my breeze, it will now barely go above 80mph.

The only change I have made, is I have removed the red vacuum hose from my air box (so that the flap stays open all the time for constant cold air). I have also turned the hot air feed from the exhaust manifold into a cold air feed.

My airbox was already drilled and de-restricted.

Have I done something wrong here? Any thoughts? I'm going to try resetting the ECU, but if that doesn't work I can't understand why removing the flap function and hot air feed would cause a power loss......... shouldn't it cause a power gain?

Or maybe my car just needs a good service!
Please help!

The obvious thing to do would be to revert your changes and see what happens.

You won't get any gain from those changes either, you'll just get a nice noise from the air box.
