Neither gd nor bad. That's right where they should be. A better question is are you happy? If yes, then the numbers, regardless of what they come on at, are irrelevant.

but that is to be expected, correct? they also are lower than a Maggie equipped unit.

for a L99 which is all that matters to the OP i think they are in the correct range.....

It feels much stronger so i'm happy with the numbers, although I've never really pushed the car yet. Still only have about 650 miles on the car. The one major difference that was noticeable immediately was the AFM being disabled. I thought it sounded terrible when AFM kicked in prior to the tune. Now the car sounds good. Video will be posted soon.

Congrats and let the madness begin!

With only 650 miles on her now, it will only get stronger as the motor breaks in...

For the L99 those numbers are right in-line. Still glad I got the Auto.. faster than the M6 off the line ..60'. Also a couple things why the M6 dyno higher are ..less drive train loss and their 4th gear on the Dyno is closer to 1:1 ratio than the Auto. At the track is what matters and that's where the Auto shines.
