I had it and I really liked it while I had it.
If you are giong to keep the edge then do this...
put hard shifing on so your trany wont slip as much, trans slip protection on, tc lock up on, 100-60% defuel 100 would be better but this is a personal prefference, I like it at 70.
think about this... the only way you will shortin the life of the trans is if you extend past stock numbers. You also have the ability to put it on hard shifting which will lock up harder, now you can go past stock HP and still be good, to an extent, knowing that extend is hard to tell. This is conserning WOT.
you can be on level 5 and never exceed past the trans limit, by your foot.
I ran it on level 5 (for eco) with "low boost adjustment" on 1 because 2,3,4,5 is just waisting more fuel by making it more ajile and smokey. this was for DD not for having fun...
I tow 10k and cruzing I had it on 4-5. Once I got to a hill it went on level 3, then on a bigger hil level 2. I never let the egt's get past 1,200*
