If you stay at or below 450wtq and make sure you don't forget to downshift to 4 before giving it beans on the highway, you should be fine. Staying out of peak tq range in gears 5-7 is important. My single turbo makes peak tq around 4k rpm, so as long as I remember to downshift to 4 on the highway before a pull, I'm consistently ahead of my tq curve redline shifting into 5th gear. It's deciding to gun it from cruising speed/rpm in 5th 6th or 7th that leads to slipping.
