^^well, i was detonating badly on the OTS map, so i dunno man, could be. i would drive it around easy, and i would take your second choice as well. if you have money for a tune, i would go to a different tuner, and get a reliable tune.
my heat shield is nowhere to be found, and I personally don't think that had anything to do with your numbers.
also, you're saying they weren't watching your AFR's or anything while it was on the dyno? is this a known tuner or just a shop w/ a dyno?
