i've heard that Superchips is a very good choice for getting a new chip, but i just wanted to get an opinion before i bought one. i have just about every bolt on done, so i also would like to know what kind of gains i can expect, and also if anyone has any other suggestions for either chip manufacturers, or for other methods of computer tuning.

I had good performance gains with a Hypertech chip on my '88 so you might want to check them out before you decide which to get.
