Have they updated these canned tunes to be better? I have a 3015 for my 2011 eco running the 87 canned tune and I just updated it tonight. I've had it for about a year now. Have they done anything to make these tunes any better?The SCT OEM canned tunes left a lot to be desired a year ago. Now they are much better. At the level of the custom tuners, likely not. But certainly tolerable and enjoyable over the OEM tune.
