The downshift threshold seems to be much lower, meaning RPM's are much lower when braking. I get some minor vibrating around 700 RPM when decelerating.

Hmmmmm should I then not update, and stick with v1.3?

I have the rumble problem and it was there before xhp tune and the tune for me made no difference. It was introduced when I add the rear subframe inserts but disappears when the engine is really warmed up. I was going to realign the rear subframe but just haven’t had the time to mess with my car. I’ve also been chasing a high speed vibration too, in 95mph+ range by 115 my car is reallly shaking.

I like v2.0 a lot more than previous versions. I was on v1.1 hybrid prior. I'd just say keep your trans serviced. Could even be harmless, maybe it's just hitting a resonant frequency the dampers and mounts have issues dealing with. I'm not an expert, but I wouldn't imagine the torque converter will be no worse off than the absurd amount of slip you get with the awful stock tcu. I plan on keeping my car forever and I'll keep running v2.0 until the next update, though maybe eventually I'll go for DWR's tune.

I personally not having a rumble issue with the 335d, but i guess trying the v2.0 wont hurt. but wondering if the update had a flaw. Buuut since I've yet to get an answer, how are your shifts at WOT between like 2-3 or 3-4, at higher rpm. when on track i noticed a significant jerk between shifts. any changes with update? (my car is awaiting a dyno tune so i cant test this out myself )

Haven't done too many WOT pulls in S mode, recently replaced my thermostat and haven't gone too hard before that. It's pretty different for me, mostly because I'd usually go WOT in D mode, and I was effectively stage 1 with v1.1 hybrid. I don't have any tracks near me and I don't use sport mode a lot, mostly to not put too much stress on the trans since the changes are pretty fierce. From the limited times I have used S mode and WOT, I'd say v2.0 is the just about the same as the previous version. Little rough, but I just assumed its the speed of the shift and the clutch grabbing hard. Someone else can probably give you better feedback.

My main complaint with the old version was the 3-2 downshift. This newest version is definitely an improvement, but I've still had a few somewhat harsh downshifts, all at slow speeds mostly going around turns and up hills. Probably not ideal. If you already have stage 3, I say upgrade to v2.0. You can always change back if you don't like it, only took me about 3 minutes to flash to the newest version!
