A tight converter will almost always be less consistent than one that is 'correct' (definitions may vary) or a little on the loose side. A loose converter can also be less aggressive on the starting line even though the RPM is higher.

The 'hit' will be softer if you lower the chip, no matter what the converter flash is. The car will begin moving while the engine gets up to the flash point, which will take some bite out of the actual hit when the engine reaches the converter flash stall point.

How you want to set up your car depends on a lot of things. I don't know how bad this loose track is and what percentage of your racing will happen at that track. Looking at it from the outside, my thought is to optimize your combination for a good track and, once that is accomplished, do whatever you need to do in order to make it work on the bad ones. That could be a shock adjustment, pull timing on the starting line, lower chip, shift 0.1 seconds into the run, etc...
