Can I get some feedback on this message I recieve. Car feels like it's running on 4 cyls when this message appears.
When I return it back to the stock air box the problem goes away. The problem seems to happen when outside temps exceed 80 degresss. I've reajusted the blue silicone adapters but still have the same result. I'm guessing I have a vacumm leak somewhere?

Your tuner should tell you the problem? Did you go over the rev limiter at any point.I personally haven't had that problem, but I know somebody who did and he had to reset his tuner.Ditto on calling Brent at Brenspeed.Should be a simple fix.
