I only put in 94 octane Sunoco gas??
should the APR program cause the car to "run rich"???
Other that using more gas is running rich a bad thing??
Sorry the noob questions I know very very little about engines and such.

i think if anything shouldn't the programs
make the car run a little leaner because isn't that one of the ways they create hp is by tuning the AF ratio? (not sure on what the programs specifically tune) Running rich can lead to fouled plugs but it depends on how rich you're running. did the dealer say anything else?

apr stock program has the exact same outputs as the stock a/f ratio...
and the performance program similary runs just as rich. These cars to run very rich at WOT to protect themselves. Shouldnt be a problem. cheers! Mike

Maybe APR can chime in here?.....
The APR stock program causes your car to run Stock.
But... perhaps they force an earlier stock calibration in the car?
Working for Superchips for 4 years, the programmers I wrote tunes for would first upload the stock program, program the vehicle, and could be restored to stock on demand. The "stock" program was the same one the car started with, so it truly went back to stock as if the PCM/ECM was still a virgin.
This was important, because there were HUNDREDS of different stock programs. (new revisions, different climates, etc...)
There were tuning companies that just forced a particular "stock" calibration they chose to use when setting cars back to stock, and it was often an earlier revision than the car had before tuning.
This isn't necessarily a bad thing if there are only a handful of stock calibrations anyway.
Not sure how it works with Audi, and I'm not sure how APR (or Revo or GIAC) handles it.
Maybe they can shed some light on this?
