Hypertech thermomaster Prom chip for 1990-92 350 TPI auto trans. Requires a 160 thermostat. Provides an increase in acceleration and better driveability. You will need the adapter or a moates G1 adapter to run this chip, as I don't have one to sell with it. However you can pick one up from moates.net for $35. https://www.moates.net/g1-memory-ada...-etc-p-32.html

Asking $55 for the chip
