I have on tried the 87 tune. You can tell a difference in power but not a lot of savings on fuel.

Used Cortex Programmer with, K&N intake, and Magniflo muffler. Around town MPG improved 1-1.5 and Highway about the same. More power, shifts are smooth and engine sound is awesome. Programmer was easy to install and I am not a car buff. Once you program the computer you un plug it and are good to go.

This works great.Instant noticable difference.Love the flexibilty for vehicle configuration(CAI,Modded Tranny, Catback).LOVED raising the 100 M.P.H. speed limit governor. Shifts firmer. Much better throttle response. Only issue I had was a few connictivity issues to my phone (Motorola Atrix)but once I went on Superchips forum I found the solution. I'm glad I waited until Superchips released the LinQ and didn't order the entire Vivid Paq with the Archos that's great for people without Anroid devices.Good to see that a manufacturer thought about Android users before iPhone/iPad users.
