I loaded the 87 tune and it felt as strong as the 91 tq tune, but peak hp/tq numbers show the 91 tune is slightly stronger. Running an 87 tune on 91 octane results, at least for me, in a rich A/F.

I posted my dyno numbers in another thread under dyno pull with magnapacks. When I did the dyno pull I had 91 octane. Using Bamachips 87 tune. I got 293hp/303 tq. But it was running rich. With the 91 tunes (race and torque) I was at 297-298hp/308-309 tq. According to Doug there is no noticeable difference between the 91 and 93 tune.
this is the kind of thing i was looking for
now even better would be a perfectly controlled ET btween no tune, 87, and 91/3
but that has too many variables
