The gains are fair, and theres gonna be another update coming with a different fuel ramp rate that should make it better. Can't really say too much about all out performance. With the cooler weather (i'm in NYC) and the V's summer tires, theres no stick, so really laying into it to check the difference is kinda not possible.
The TCM updates are nice. They chose to have 2 different versions, one just slightly firmer then stock, and one harder one, so you can set it for personal preference. The Hard one is great for me. I like to feel my shifts, and they're certainly much faster.
The tune is setup for the stock T-stat, but if you have a 160, you can easily lower the fan turn-on temperatures.
When it is released, I would absolutely recommend it. I hate having to send in my PCM for tuning. It leaves the car dead for however long it takes, and if you do another upgrade, you gotta send it in again. Tuning with the Trinity (or soon the InTune) takes about 5 minutes, and if you need an update done, you call a tuner with the CMR software and they can update your tune and email it to you (for a small fee). Its much preferable IMO.
