My 1989 came stock with an A9L. I did a few minor bolt-ons, and removed some emissions stuff. Getting (someday) ready for an S-trim which will need new calibration, so I got the chip now...
So I got a
www.jmschip.com chip. On a bone stock motor, with pulleys, and headers/offroads I pulled 237rwhp. This was on the third chip (of the three I tested) and made 7 rwhp more than the other two, but 12 more than stock.
I was happy.
