Rough idle, Lean AFR

Turning the wheel actually presents load to the engine; that's normal. Similar to turning the AC on.
You may need to reconfigure your catch can setup with a check valve to only allow air to flow to the intake. It's not a tune issue.

So this is the current setup for the catch can, if you don’t mind, where would I put the check valve or additionally check valve?

DM PCV plate/PCV valve >>> OCC (vented to intake pipe) >>> intake manifold with inline check valve

[mention]Awafrican [/mention] concluded my testing today, results are as follows;

Boost leak test yielded no leaks. Put approximately 30psi into the system and plugged it, no leaks and held pressure.

Smoke/vacuum test - yielded 2 very small leaks on the hoses for the oil catch can. Smoke was leaking through. Removed and reinstalled clamps. Ran smoke again for about 5 minutes and both leaks were closed.

Compression test was done - left to right; 210, 190,210,190

Found MAF to be loose and o-ring broken the other day, it has also been resolved.

Everything should be in working order now!
