RPM's are sticking

I just installed a AFE stage 2 CAI. And I just drove it around for about 30-45 min. Just sometimes when I was cruising the back roads I was going about 45mph or so and everytime I let off the gas the rpm's would stick around 1500 rpm's instead of falling down to where it idle. What is causing this?

truck might be trying to enter or has entered regen since its seeing more air so computer puts in more fuel and then is clogging your dpf so it has to enter regen to burn the built up soot out. Just a thought. You shouldn't have that issue once your tuned though
