I willl test using my EGT and a timing light to see.

It's hard to say for sure because some tuners have used the FQS switches for fuel injector sizing. You can change the FQS swtich on the fly while the car is running. So it's easy to test the behavior with a timing light and AFR meter. If you go up one position and there is no timing change and little fuel change it's probably set up stock like mine. If it goes way lean, then the FQS are used for injector sizing. But as far as I know from what I've seen, the top 4 positions still mirror the bottom 4 on fueling and incorporate the timing retard.
Your mileage may vary...
