I'm going to make this thread in hopes that it helps someone else out in my shoes. I live in the Midwest so I had to do remote tuning(we will get to that later). I installed all the parts Headers, High flow cats, CAI,TB, Flex fuel Sensor, JMS voltage booster, AEM Wide band. This won't be a step by step as their are plenty of them out there but just tips and tricks that helped me.
We will start with exhaust. Headers and high flow cats were simple install. If you are going to be remote tuning you need to make sure to weld your Wideband bung in. I welded mine in the high flow cat flange BEFORE the cat. I also went ahead and purchased this exhaust sealer and used it very strategically on all the connection spots.

The flex fuel sensor is self explanatory install. I purchased wire loon to hide the white wire. You might want to do the same. Get small black zip ties.
The big gulp CAI gets shoe horned in there, so prepare yourself. Throttle body easy peasy.
The JMS... This thing was a pain. I'm just going to ramble here. Before you install. PUT A FUSE AS STATED ON THE WHITE WIRE, this makes it easier to take voltage readings when installing. EXTEND THE RED WIRE. I would add 12-18 inches to this wire. You can make it reach but you'll want to add wire in the end to make it work nicely. I used the not cut method found here with all the parts:

Have zip ties ready for the JMS wires for under the car. Have velcro ready to keep the JMS module attached to the trunk.
Programing this thing was a MOTHER f'er. I bet I jacked with it for 2 hours trying to program it. It would not take. It wasn't till it started flipping the number 1 switch around many times and finally it started to program. I'm not sure what that was about but weird. This was easily the biggest time sink of the whole project. I still might go back and do some wire cleanup. There is a grommet on the driver side trunk to go through. I ripped mine clean off but will be replacing it with some I bought of amazon ill attach here:

AEM wideband install - This was really easy. I used a grommet from the amazon link above to go through firewall. I pulled power for the wideband with a custom harness from gen5DYI tapping into AC control module. Their harnesses they use for Radar detectors but my gosh, This was slick, Plug and play. They just added about 5 feet of extra wire to pull power to the drivers side. I high recommend anyone doing a wideband to get their harness from GEN5DYI, no cutting wires in a harness just plug and play.
Tuning by Ted - This was way simpler than I thought it would be. The hardest part was being able to get Ted the data he needed. The new found power would blow the tires off. Be prepared to do 3 or 4th gear pulls if you don't have radials to get the data he needs. Took about 6 tunes. I honestly loved the data logging and tuning part. Thank you Ted for all your help here. Highly recommend his services.
Final thoughts - The car is an monster compared to what it was. I my PS4s are going to need to be upgraded. I thought the car had new life on the 91 tune but when we got it to e55, it was a whole different car, it ran smoother as well. The car is still kinda loud in stealth mode at start idle but I'll deal with it. Cold starts are pretty crazy even with HF cats in track exhaust mode( I came from a big cammed c6 and that was 4 times what this car is sound wise). I suppose a cam is next but hoping my oil pump holds out for a few more years till i get time to do that. Anyways, the package is a nice touch to the car without getting to invasive and keep engine bay looking stockish.
