So far so good with mine as well. Here's what I have noted with just a couple days playing.
1. Needed to learn how to drive the truck due to the changes as throttle response seems to be way different in my truck. If I drive like I used to with medium throttle from a dead stop, the 3tc would lock in ~40ish and jerk the truck pretty harshly, thinking that's because I'm letting off the throttle right when it locks so it was basically bad timing on my part. Around town speed limits are 35, adding to my issue. Resolution was to lightly accelerate and haven't had the harshness since but again I only press the throttle about a quarter inch to get this and maintain speed.
2. Like others say, this tune drives the turbos hard. Before the trans tune peak psi was 38 and now it's at 40psi.
3. 3rd gear once TC locks is like a freight train.
So far loving the trans tune... Forrest, the other tune is a monster as well. Sorry had to check it out.
