I was not aware they could be reproduced. Would it be the same as the stock, as my ultimate goal is to take this car completely back to stock configuration. Please advise on cost as well.
Thank you,
There were many stock chips in 1986/87....I think Buick produced up to 7 updates over the two year period. Some were much better than others at cold starting and part throttle operation.
Not sure if you found one or not, but if you still need the chip, I have a late model 87 GN chip here shipped to you for $15. I didn't see where you are located, so that price w/ shipping is in the 48 states. Email if interested
