I have a few questions about tuning. I already have an SCT SF3/X3 tuner and I was curious who everyone would suggest for a tune for my Automatic 2012 GT. I had Bama on my 2005 V6 and didn't have a problem but am willing to look into others. I can get the Bama tunes for life for $150, John Lund tunes for $200, AED tunes for $250 or finally VMP tunes for $120. I don't really mind the pricing at all but figured it would help you decide which to suggest. Is AED worth the $250 that it costs and so on. Also if there is another tuner that you would like to suggest, please feel free to help me decide.
