Wish I did a baseline run for my car too. Just found out there's a dyno place near my house so I'll try to get it done before I get the next Dinan performance mod.

So you got a gain of 9hp? You're talking about Crank HP right not WHP... if its WHP OMG THATS SOOOO GOOD!

OK, the issue is not clear yet. What is pre-tune WHP for 550i? That needs to be answer, and I guess it should be ~320 hp at the rear. I want to know, too.

Yeah, parasitic losses through the drivetrain will take about 20% of the crank HP away so I'm sure he means he got 369 crank HP, not WHP. If he got 369 WHP that means he gained about 100 horses from a chip upgrade.....WOW, that would be awesome!!
TCAOS, price-wise, I would consider 9 HP pretty good since I know Upsolute only charges about $400 for the programming. Most exhausts won't give you that much gain and will cost double or tripple. On the flip side, when I talked to them last, they said the average gain would be around 18-20 HP for a 545 but it would depend on the car. Let us know if they're able to improve on the numbers...good luck!

9HP over 3800lb car does make any difference since to get that 9hp, you need to rev a little higher. Increase by at least 30hp would make sense to do. Just my $0.02

Sorry for the delay. The Dyno run was crank not rear wheel. The cold air intake was not put on due to the mixture being off. I feel that 9hp is not a good gain, I feel it gained the extra HP from the B&B and a K&N filter I have in the stock box. Upsolute at the least calls for a 15 - 20 HP increase. The decrease of HP through the drive (SMG) was 20%.
