Another YT video with some more progress. Custom Twin Disc clutch is installed, a few leaks I got have now been fixed, turbo got reclocked, Vaccum lines to 4 port Mac were mixed up causing overboosting but are now fixed, and a lot of other loose ends have been tidied up to get the car 100%. Here is a video of some pulls on wastegate at 93 octane, the slowest the car can possible be with this set up and its still much faster than my last FBO 135i N54 car was.
Since this video, Ive done a few more things such as CDV delete, stock trans mounts back in (now I have zero NVH with this and 900 RPM idle), new 02 sensors, and revision 4 of the tune flashed and car is now making 17PSI. I will post a new video of some more pulls / explain a bit of the street tuning process when I get more updates of the tune and its near completion as well as the E40 tune!
