wait4me performance pcm questions

I am considering buying a custom tuned pcm for my 96 blazer. Besides improved gas mileage and added horse power what other options are available when i tell him what i want to see out of my tune?

I'll be ordering one within the next few days as well. Other than engine tuning, Jesse can change transmission settings like line pressure, shift points, and torque management. He can also tune out things like O2 sensors, EGR, etc. Tell him anything you can about your truck like any mods, what you use it for, etc.
