6637 Installed; now swooshing

I've had my 2000 F250 PSD bone stock for 5+ years and never any problems. Today I installed the Riff Raff 6637 intake. Power, response, and shifts are good. However, there's a noticeable swooshing when letting off the gas at 2,000 RPM to about 1,500. Is this the infamous surge that I've read about coming from the turbo?

Is this normal to be experiencing after a 6637 install on a bone stock PSD!? I hate to think I have to drop another $90 for a WW to get the surge to stop just because of an intake mod. Any advice?

I have a 5" turbo back straight on the way and PHP tunes on the way. Wanting to nip this in the butt before I add more mods.

Thanks for any insight.

That is not surge. That is just air escaping back through the intake because of the decrease in RPM's. It is completely normal, and it happens with the stock intake kit, you just don't hear it.

Surge will occur usually at higher boost under a load. You will hear a fluttering sound.

did that kit come with the ring that goes around the filter and mounts to the battery tray?

I don't mean to hijack your thread. Just wondering because i currently have a knn intake and want to switch over to the tymar kit. The tymar kit looks like it keeps the 6637 filter off the fender with that ring mount.

No ring with this kit.

The tip of the filter on the bottom rests on the fender but I would say 95-98% of the filter hangs in the air due to the strength and pitch of the OEM hose. The kit literally includes a cuppling, a band, the filter, and a sleeve to cover the filter that can later be washed.

I see the ring you're talking about though. I haven't heard of too much water damage issues but I can see where the ring and batter tray come in handy. I think there are cheaper ways to keep the filter off the fender 100% if fearful of water and mold damage to the filter.

I think I'm just going to order the tymar kit from beans diesel. I'll eat the knn intake or try to sell it.

Here's a pic (not my setup) but mine is exactly the same. From Riff Raff.

Scroll down half way down the page and you'll see the motor w/intake shot:

You know the Ford AIS system, looks better, breaths better, and cost less - right?
