PCM for less question

how much of a difference will I notice in my 97 Z28 with a PCM for less tune?
what settings does the tune change?

Generally mail order tunes can see 15-20HP gain on stock or bolt-on LT1 cars. It can vary depending on the condition of the motor, types of mods, quality of fuel, etc.
