I purchased a 87 grand national. This chip was sent to me with the car. Does anyone know anything about this chip. Or does anyone have any advice to give me before I install this chip.
This is my first post. I have a 87 grand national. The seller gave me a chip with the purchase of my grand national. The chip reads ( thrasher 92-28-k2 ) can anyone tell me what this is or have any input on what I should do before installing the chip.
