ADS Super Chip for 87 GTA 350

I just discovered that my recently purchased 87 GTA 350 has the ADS Super Chip in it. But… what I don't know is any tuning specifics (timing, etc.) that go along with an ADS Super Chip application. I would very much like to know this info as the car was purchased from a dealer and I think they may have tinkered with it to get it thru emissions… and I don't think they have it set up just right for the chip.

If anybody out there has this chip in their GTA I would greatly appreciate your help. Thanks!

I run a Hypertech Thermomaster chip. Summit informed me that ADS went out of business recently. The chip usually alters the timing and fuel curve at 80% or more throttle, depending on if you have a street chip or off-road/strip chip. Should not affect your emission test either. The computer looks for a correct window of timing, otherwise the car will hardly idle and run like crap. This is using 36-38 degrees of total timing. Should not have any problem passing as long as you are running a Cat and the air injection system into the exhaust. It will pass with these items in place and you can still use a 160 degree thermostat.
