I've posted a few pictures of my issue with the revving. This happened as I was leaving work to come home yesterday. I started the car, it revved higher like normal until it had warmed a little, a few seconds, completely normal. Then it revved down. Take off down the road. A couple miles later I go to slow down and the car feels different. It isn't the brakes themselves that feel different, it is like I can feel the car pushing to go forward when I am trying to slow down. I put the car in neutral, viola, car revs up to 1500 RPM. Put it back in drive, proceed home. These pictures were taken in my garage once I got home. The ones where it is revved up are when I pulled in the garage. I let it sit for a few minutes and it stayed that way. So I shut the car off, then started it back up, and the tach was pretty close to normal when I restarted it (shown in picture.)

Any ideas? I email the person who did my Eurocharged tune a couple days ago and have yet to receive a reply. I checked the brake booster, valve cover, and the t-like vacuum hoses and they all seem fine. The brake booster vacuum hose is having to bend just a little bit around the MAF sensor on the new intake, but it seems fine.
