All, I just did the DIY Tymar intake on my 2001 7.3 SD.

Here is what I want to ask and want to know.

As most of you I have spent hours looking into this and now that I have done it I am starting to think a little bit about switching back to my AIS System. Here is what I think so far:

1. Turbo - spools quick - sound is the following: Sppppssssssssssssss let off the pedel and you hear it unload sssssssssssppppppS. Sounds good but my question is: how will this sound on a long trip on the highway driving about 70mph for 4 hours? Will it do any harm? (Has anyone had issues with this)

2. I did this mod Tymar as a proof of concept, but I am torn on the idea. Should I go back to the AIS Intake? Should I run this Tymar for a bit and see? (I just put this on 3 hours ago).

3. Is there any issues, burning up the Turbo? I noticed that my AIT F, Air Intake Temp is a little higher now usually with my AIS it was reading more the outside temp of what it was sucking into the AIS System, now that I have relocated my AIT I noticed that is is ready temps higher than what I was previously getting, like this evening its in the 50 or 60's and the temp reading I was getting was about 85- 95 degrees. Downside to this? or not to worry about this since the sensor is not in the box as it was when using the IAS.

Any help would be very much and kindly appriciated.

I think you are fine. I run the 6637 filter myself for almost 2 years now no issues. The whoosh noise you were talking about is just the turbo sucking in air then when it shifts it cant use it so its pushed back the only way it can which is back out the intake. Perfectly normal
