Happy to report successful CP3 swap - 2013 JSW 2.0TDI, 6spd after some initial trouble.
Simultaneously did T-belt, water pump, idlers, t-stat, harmonic balancer, lower cover, full deletes + stg 2 tune. Took about 40hours to do it all, but it was my first time doing "major" work on this car though.
I will say, a third of my time was me trying to do my own DIY tune on a nickel, made it about 95% of the way. I was actually able to turn off the DPF and EGR (and tuning protection). It was drivable (drove around a few days), albeit stock power and all the DTCs were still on. While I was able to see maps themselves to attempt a stage 1 or 2 tune, I wasn't confident that it had interpreted (or "mapped the maps") correctly, in the decimal grids I was seeing erratic values instead of smooth gradients along what it thought was load/rpm/airmass.
I've done my own tuning on GM stuff with HPT and I could definitely see the parallels, but the knockoff software in this case sucked and/or seemed more geared towards euro spec cars. I found myself only able to find an approximation of my car, not the exact and usually only up to 2011. I still have my original and DPF/EGR modified binary files so I may try again in the future, and possibly document what I found so far, if there is interest. Most available info seems to be from across the pond. There is definitely a big learning curve, and admittedly, a substantial risk, in front of this knowledge, but to technically perform the read/write is a laptop + ~$160 in aliexpress hardware (which I actually had no problem with).
In the end, I wanted to get it back on the road and verify the work I did was good, so I ended up paying the big bucks, (more than the delete itself sadly), for a premade tune, which had no problem overwriting my slightly modified tune.
