After more months than I care to add up my 19T has finally been rebuilt. I can't really complain since I told them I wasn't in a hurry and they took their time. Apparently they did some more porting and polishing on the housings and replaced all the bearings/seals on the donor cartridge. They also sent it off to a few other companies to get second and third opinions on the assembly. I expect this one to last a bit longer
Assuming time permits, I'm picking it up on Friday and installing on Saturday. Give it a week to break in and I'll start to tune and have fun. I'll do my best to find a free night this week and log some WOT pulls with my current stage 2 setup for comparison.
