Thank you for putting that video together, great testing methodology.
I recently purchased a 01 986 s that already had the fabspeed headers / maxflow exhaust and I think the sound is incredible. My last "fun" car was a chevy ss with an LS3. I thought I was never going to enjoy the sound another car as much as that ls3 and I was wrong, the music is just in the higher revs now.
I am going to research ipd intake, I agree it sound like a lot of power on the claim side.
Question on the fabspeed tune you have. One thing I noticed about mine is that I have less emissions monitors then I am used to seeing (was not a problem for my ny emissions test). All the monitors I have are green and there is no sign of any issues, but there are just less.
This first image is a scan of the boxster with a basic innova 3100
This one is the boxster with a foxwell scan tool
And this final one is to contrast, it is my 2019 pilot with innova
I know the pilot is much newer and might have additional monitors from 2001, but I am pretty sure there were originally more than 5. Have you noticed anything like this since you got the tune?
