I purchased the PCM Stage 1 for my 170,000 mile, 2005 Chevy Silverado (5.3), not for racing but for towing. I found the directions less than impressive as my chip was by the power steering pump under the battery. Softer shifting and less aggressive pedal but when I hit it I heard the valves rattling because I had not upgraded to mid/premium. Performance from 0 - 22 (still tired) but 24-70 WOW. So far I 0-1 city (my fault - aggressive driver) and 2.5 mpg (average so far) highway.
