That's actually a good point, never thought of it like that. I thought that the K04 TCU tune would account for that but I suppose my custom tune + HPA turbo delivers torque differently vs APR's (HPA does claim more torque down low).
But would this affect downshifting too when no throttle is applied?
The only thing I can think of is that when your engine and transmission are communicating on a downshift they’re not in sync with each other. Your trans is expecting less torque but the engine is ready to provide more and maybe that’s causing a hiccup. I had strange down shift problems from time to time to on my strat k03 tune as well, but my trans and motor mount were toast, but I can only assume that was part of the problem, not the entire problem.
I upgraded all of my mounts when going k04 and like I said had my tuner tune the car to have a linear powerband to lengthen engine and trans life and all of my worries about my dsg exploding or my mechatronic unit being bad have subsided. I really thought my trans was toast for awhile on my strat flash tune.
I think some tunes out there have torque coming on way too abrupt and I don’t think the stock dsg likes / can handle it unless you have upgraded clutchpacks.
I miss the thrill of blowing off tires like it was nothing but spinning ain’t winning and torque breaks shit! I just launched my car for the first time last night and I actually had good traction and moved rather quick instead of sitting there roasting my tires.
If you haven’t upgraded your mounts I would start there but for what it’s worth I think you could also look into a retune and have your powerband adjusted to something more linear instead of peaky and punchy down low to see if that solves your issue.
It’s times like these where I realize the manual is superior to the dsg. Upgrade clutch; boom done; give it hell with all the torque!
