I can tell you about my experience with the drives. I installed one on my mostly stock (3 inch downpipe) 94 6.5TD Blazer and set the timing to -1.94 IIRC. The engine became more responsive and the throttle response was a lot more crisp. The engine also liked the higher end of the RPM scale whereas before it would struggle along at highway speeds. Low end response was really enhanced in my opinion. From a noise perspective idle was a lot louder, similar to what you would hear on a really cold morning. It sounded better so I didn't mind that. Mileage seemed to improve a bit but I don't have data so take that for whatever you want. On an interesting note, the technician who set the timing for me commented on how little variation there was during setup. One could speculate the pump was more effective at delivering fuel due to reduced timing variation = smoother overall operation.
Granted, the new timing and gear drive produced the results I observed and I don't have experience running the advanced timing alone on a stock drive or running the gear drive on the stock timing, but I do believe they both work very well together.
When I sold the Blazer and picked up my Suburban I didn't think twice about getting another.
