I have a question about custom tunes on the 05 GT and have the SF3 tuner. I know Dan and others from American Muscle monitor these threads so whomever can chime in would be awesome!
I've been running custom tunes for about 1 1/2 years since I picked up the 05 GT. I recently added the GMS Throttle Body and grabbed some replacement tunes (free tunes for life member) from AM and Bama. I noticed that when I went to load the new tunes I didn't see any options for changing Octane, CAI, or Throttle Body when I went in to the tunes to check them out. Strangely enough when I go into the "Strategy Tune" option on the tuner instead of the "Custom Tune" section I DO see these options and am able to change them. My guess is they are hidden from me in the Custom Tune section so I can't change them?
The reason I ask is because when I got the 3 new tunes I felt like my car took a step backwards as far as HP and Torque. This is why I noticed the tuner programming differences and was checking them out to see how they were set up. I DID contact Bama for 3 new tunes, but only to change the octane on the perf tune. When I loaded the new perf tune, this time it felt like it was tuned correctly.
Was it a coincidence, I don't know but I just want to make sure something isn't up with the tunes and tuner. I haven't had a chance to call Bama to verify so in the meantime I figured I'd pop on the forums.
