1. Stock F10 550 that I currently own was dyno'ed by Dinan at the similar HP as rated by the factory, while TQ was about 55lb higher.
2. Stock G30 550 was dyno’ed by Dinan at about 85HP and 115TQ higher than the factory rating
Is that really possible? Are you using the same Dyno?
3. G30 Stock vs tuned delta is about 50 peak HP and 55TQ based on your measurements and brings the total measured 590HP and 650TQ
4. Dinan claims that S1 package (includes this tune, midpipes and exhaust) delivers 606HP and 625TQ
5. Dinan also claims that this S1 G30 produces more HP and TQ than F90 M5
What am I missing here... if your dyno is measuring consistently higher than factory, shouldn’t you wait to dyno f90 M5 before this kind of claim is made? Dinan focuses on 600+ numbers instead of simply claiming about 50HP and TQ above factory rating… I understand that you are a business but this kind of marketing…
F10 550 tune is $2600; G30 550 tune is $1700… Is this introductory pricing?

1/2 - Yes. Same Dynapack dyno. Was also measured on APR's Mustang Dyno when the car got back to Alabama and came back with the same numbers (within a 2% variance).
3/4/5 - See post #3 above but the S1 that was originally put out to press was measuring a bit higher in HP as it was a slightly different tune. We sent the M550i down to press while we were doing our relocation to Alabama. Rather then have the car just sit around idle for weeks on end we opted to get some test miles on it and get some publicity while we were down. When it came back we took a look at the logs and also some of the comments the reviewers had and revised the tune from peak numbers of 604/635 to 590/650. Everyone who drove it seemed to want more grunt down low then top end so we obliged in the final iteration of the tune.
Also a caveat for #4. Every single press article kept claiming the mid-pipe was on the car when it was not. The sheet that was given to the various press outlets noted that the midpipe is coming down the road and would be available but all assumed it was on the car when it was not. It is still in initial prototyping stages. Lesson learned for the next press run to not try and give them "coming soon" listings.
5a - We just picked up our F90 M5 back from the dealership after the break-in service so it will be going on the dyno for baseline next week (have some M550i / M5 comparables for wheel fitments and everything this week before the M550i dissappears on a MINI-press jaunt on Friday). BTW, Dinan never claimed it made more power then the F90 M5. That is media simply comparing tuned numbers to factory numbers (which will undoubtedly be underrated).
5b - Again, the press is focusing on the 600 numbers. In listing of the product we give about every major data point in crank and wheel numbers as well as the peak numbers so you can formulate as much of your own opinion as you want. Even in the banner above we focus on the gains and not the overall peak numbers.
5c - Not an introductory price. The F10 550i harness plugged directly into the DME where the G30 M550i harness is connecting to multiple sensors. The F10 550i harness is MUCH more expensive to make and as a result retailed for much more.
