IMO, absolutely worth it. Here's my experience...
I have both the Dinan DCT and engine software, nothing else. I had them installed individually and could notice a difference with both, though the DCT software made a bigger difference than the engine software.
Recently I had my dealer code/activate my car following an OEM alarm install, and in the process they erased all the Dinan software. On the drive home something didn't seem right. Then I noticed the car going into manual mode (Dinan DCT software defaults to auto mode) when putting it in gear, the shifts were clunkier, it didn't run as smooth, especially when cold. It was obvious they'd erased the Dinan stuff.
The dealer re-installed the software and it made such an improvement. While inconvenient having to take it back it, it was almost a blessing. Having it installed, then erased, then re-installed, I could really appreciate the improvements and it made the cost well worth it to me, both the first time, and especially the 2nd time.
The 50% sale is over but I think they lowered everything 25% following the sale.
