I have found that the T-series is a bit underpowered and the transmission to be, well, off. I also found the brakes to lock the wheels up much too easily. So I adjusted all three. The stock T-series has ~1330 ft/lbs of torque and 425hp. After my adjustment, it has 1475 ft/lbs of torque and 430hp. As for the transmission, I have adjusted the gear ratios and turned the first gear into a crawler gear (still needs a bit more adjustment). I highly recommend that you do not drive with arcade automatic, although the truck will still run fine in that mode. This is compatible with Dummiesman's trailer mod.
