Maybe this is normal but I don't think it is at all.

If I rev the engine and let go of the gas, the car will backfire just after the rpm peak. Doesn't always do it, I think it only happens after 3500 rpm.

Also, I just did a tuneup but I seem to remember this happening before.

What could be the cause, and how could I fix it? Car has about 54k miles.
