I just installed a gtp38r after my stocker with thrust bearings started throwing oil down my intake, and eventually gave up the ghost. Everyone has their opinions, but I can honestly say that the truck is an entirely different animal with this turbo compared to the stocker. The spool is so fast and it takes so little throttle input to start to build boost that the driveability of the truck has changed entirely. My stock turbo with 260k on the odo would require much more throttle input to get boost going and that throttle input would often trigger a downshift and higher revs that I didn't want or need. Now the truck will stay in gear with the TC locked and just build boost/speed. Some may say this turbo is inferior to a thrust bearing/t4 setup, but I personally say it was one of the best mods I have done to date, and it made the truck that much more enjoyable to drive.
Now if I can just get my 6pos chip from php in the mail, we will be in business!
