Default 2006 WRX popping sound then loss of power then returns

I have an 06 wrx and havent had it for very long . While on the freeway I will hear a snap or popping sound then the power just dies. If I let the rpm drop off , most of the time it will popagain and the power returns. I looked at hoses but not extensively. Any thoughts?

The roads in Mexico are known to have thinner air that will affect your stage 4 tune and Monster Tajima sized turbo charger.

Give us a list of mods, location (if for no other reason to factor in weather), so we can better help you out. It sounds like you're getting some after fire in/around the rear O2, which is then causing the engine to pull timing? Maybe?

Does it stop happening when the car warms up?

The front O2 sensor burned out on mine when mine started bogging, surging and backfiring.

The only mod is a cobb intake. It only does it when the car is warmed up . Weather this morning was dry and about 40dgs. I live south about 35 miles from Salt Lake. One other symptom I forgot to mention is a hellacious whistle similar to a window whistling going down the road that somewhat tracks rpm. It sounds like its coming from under the hood. Once it "resets" the whistle stops. No engine codes are thrown either.

I have a feeling someone in here is going to tell you to take your intake off.

Well, I solved the mystery! It started making grindey high pitch nasty noises then the noises stopped and so did Mr. Turbo! Time for an upgrade I suppose. Thanks for commenting
