So I finally got to the point where I wanted to go 5120 to squeeze the last bit out of the turbo.
Using a 1.8t file floating around wasn't an option as I really like fknbrkn's HJ Multimap.

I tried it 2 times with completely different files. The only edits missing from the files are the divisions for LDRQ0DY and D1DY.
 Immo is disabled, files are checksummed, flashing finishes without errors.
After flashing the files the car cranks, sounds for about 1 second and then stops doing anything.
I hope someone can point me in the direction of what to look for in the log or maps.

On the main 5120 thread fknbrkn had the same issue with a 032HF file, but never posted a solution. https://nefariousmotorsports.com/forum/index.php?topic=3027.msg149186#msg149186
