I just had a Steve Wong chip installed but haven't driven the car since the install as an A/C update is in progress. There are a number of threads on this site with positive reports about this chip and improvements in low end performance. Search on Steve Wong to find them. Here in NC the '80s cars no longer have to have emissions checks so I decided to go with the Fabspeed prior to deciding on the chip. If you would like to read some dyno results Steve has them on his site
www.911chips.com. I believe I recall reading that the earlier 3.2 cars like yours have the most potential improvement. You can also email Steve with any questions; he is very responsive. Also note that you can order the chip through our host.
Regards,
David.
