Just another update as I've been away for the site for quite awhile. The GDE turbo kit, TCM and euro torque converter are still running well. We sold the TDI and the KJ has become my wife's daily driver. She makes a lot of short trips in it and the mpg's have suffered quite a bit compared to my normal to/fro work drive. After she'd been driving it for several weeks I needed it for something and was surprised to see a whole bunch of black coming out the exhaust the first time I got on it. She was babying the thing and I encouraged her to every once in awhile, when the engine was warmed up, to get on it a bit. Haven't had that issue since
