I stopped up to the shop yesterday for a few and the car was off the hoist getting wiring worked out. A couple wires were re routed here and there, connectors added, wires extended, trigger wires going to the ECU, and a few other items that I'm sure I forgot. All the wiring is getting labeled and documented. You know... professional stuff. I think for the most part all the hard cable monkey work was completed by me. All the heavy cable was pulled to the right area, ECU was pulled through and plugged in, a lot of OE wiring was thinned out, and I had a lot of extended connectors.

*edit* - The car has sooooooo much dirt on it, you can not see through the rear window. It's nuts. For the record, I was pretty insane about keeping my car washed and waxed prior. Madwi offered to help me do a quick detail on my car... I will take him up on that offer. lol

While I was at the shop, Dave mentioned to me that it would be a good time to get the MAC valves ordered and wired. The MAC valves are used with CO2 to control the waste gates, well... the ECU will tell how much dome pressure to add specifically which is why he wants to wire it. SO, I immediately purchased the Motion Raceworks dual MAC valve setup:

If you really want to know what the MAC valve setup is all about then check out this video. I don't really see people using it on the forums or FB. My quick explanation above (adding dome pressure) is basically like using an infinite spring rate inside your waste gates. My springs inside my waste gates are 6lb springs so minimally my car will make 6ish lbs of boost (maybe some boost creep?). THEN if I have CO2 working on my car I can pin it shut and run 35-40lbs (maybe not 40lbs because that would be like 2,000hp for 3-4 seconds until the rods fly to heaven)
