Ok, I have an update for all those experiencing the nasty DSG shifts with APR 2.4 especially in manual mode as I have been fighting with this for > 1 year now and was about to switch tuners.
Update:
On a whim, I decided since I just hit 70k I would go for some fresh sparks, new R8 coilpacks and a new PCV as well just for good measure. One of those fixed my nasty DSG shifts, smooth as butter now in D and near perfect in M even at full boost (where it was terrible prior). My theory is my PCV was failing or the diaphragm was busted just enough to not throw any codes. But now, car runs incredibly smooth, power is back to 100% (though it was probably 95%), shifts are crisp and smooth up and down and it's quiet as ever.
Cliff notes:
-Rough DSG shifts with APR 2.4 (I'm stage I)
-updated coilpacks and R8 coils to new ones at 70k
-updated PCV valve (super easy install)
-power back, smoothness in the engine and DSG shifts makes me happy with car again
-Thanks HSTUNING
-MPGs are up as well
Just an option to try if any of you are experiencing nasty DSG shifts and not throwing codes or anything else.
