Which chip for 86 5KCSTQ?

["Martin Pot" <paulnet@ipa.net>]

I am not racing the car, but I live in an area with hills and very curve
roads. The roads are mostly two lane with only a few passing zones. Since
opportunities for passing are scarce, more passing power would be very
welcome. This would mean less time in the oncoming lane, thus safer. I
wonder if somebody knows if there is much difference between TAP , Ned and
Wett chips or should I go with the cheapest? My car is getting in really
good shape, thanks to the list and Bentley.  Thanks, Martin
