Just curious isn't our PTU on the AWD a huge weak point already? From so many threads on here i figured this type of power gains would basically just be to much for the PTU. Or is the PTU not quite as unreliable as some have made it out to be on here?
I have done a fair amount of Gear lube testing and think I have found the best Gear lube to use with the PTU. Frequency of change is the key to longevity plus the extra amount of capacity that has been added to the PTU are the slight improvements with the addition of a drain plug to facilitate fluid changes. The PTU should be able to handle up to about 500hp. The newer PTU's have had some additional internal adjustments but heat is still the enemy of the lubricants.
