Headers in, picked up the car today, I hadn't installed the
powerchip yet when I picked it up, I certainly used it
as a safety factor,told the shop not to get on it when testing,
because of the powerchip. It also was helpful, that the weather sucked, so I couldnt get on it anyway. All I can say is
WOW!!!!!!!!!!!! I love the sound! I just downlaoded the
powerchip a few minutes ago(11pm cst). I hope the roads
are dry in the morning, so I can oper her up a bit!
I could feel that big grin again when I picked her up today!
Now to see how the seat of the pants:M5launch: feels! I will certainly let you know!

Knew you would be pleased. It really wakes up the car. Powerchip upload should take about 15 minutes when you get the new program back, and then the computer takes a few miles to adapt to the changes.

Agree with above. It can take at least 50 miles to "set in". You will love it. It has been a great boost for my beast. I always felt my beast was a bit down on power at stock compared to some other M5's. That's when I found out that there can be a 10% variability in output of the S62 engine and BMW will tolerate it. The SS mufflers and X-pipe gave me a great sound and about 8-11 more HP (dyno proven) and the headers and racing cats added another 25 - 30 HP (also dyno proven).

:cheers:
