Hi guys, i just bought a civic SI 2006 and when i drive it like '' normal '' my rpm's goes UP when i shift and stays up there like 2 secondes
I've read a lot about rev hang, is it that what i have ? or can it be a vacuum leak somewhere ?

Here's a quick video ( sorry for the quality ) :

What do you think ?

That's the rev hang. Youll need a tune to get rid of it.

If it can help someone, problem solved! I just replaced the AEM SRI by the stock oem airbox
My fuel trim goes straight back to normal
