That sure seems to be a stock chip. The AXKW is the BCC that identifies the GM calibration and vehicle it is to be used in. If it looks like the label has never been removed, I'd say that it is still stock.

Can check the memcal,prom sticky at the top for a pic of a stock PROM.

Looks like the AXKW BCC was used in a bunch of years. It is an f-body 305 chip, with a 5 spd manual. Fed emissions. TBI.

Noticed you have a 700R4 trans, do not use this chip in your car with an auto.

what would happen if i used that chip in my car?? would it hurt it in any way or just not run right

It will destroy the TCC. The shift light output and the TCC output are the same pin on the ECM. The code does either one or the other, manual or auto.

So, using that chip will activate the TCC each time the shift light comes on. The opposite of how it works with a proper auto chip.

TCC is the Torque Convertor Clutch. Can usually feel it lock up at light throttle above 42 MPH. Sometimes will feel like the trans shifted into another gear. Will also see the RPM drop when it locks. Prevents slippage in the torque convertor to reduce heat buildup and to improve fuel economy.
