This was the last item installed out of an AEM cai, Pulstar Plugs, Rancho Shocks, Helix Power Tower TB spacer. Before the programmer, improvements were hardly noticeable. AFTER the install, on the basic performance mod, power is definitely up, shifts are at better points / faster, and my MPG went from 11.3 to 12.8+ average = 12% increase = HUGE. It's tempremental during install, so do it with tech support on the line. I don't like that you have un program the vehicle before any service.
