The motor has nothing to do with whether their tunes for the 10-12's are ok or not, neither does anything else you brought up. What issues were there with the 10-12 tunes? I paid extra close attention as I ran their tune on my 11 up until march of last year when I sold it with 170K miles on it. 70K of those miles were with the LMS tune.
Every issue I recall seeing was with the V11 tune for the 13+ models.
The issue with the 10-12 tunes is that they're pathetically weak. But their lack of tuning knowledge and arrogance to opt not to work with DW with their injectors....messing with his car for weeks.
What you're trying to say is their email tune for 10-12 works. For the sake of your point yes...but so does stock.
