Hello,
I understand that the only thing that really matters is the delta between measured HP and TQ before and after the tune.
At the same time I have a few questions as I am considering purchasing Dinan tune for my M550.
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?
