Power Loss! Help Plz
Ok guyz, my car has about 4200 Miles on it, and I don't know if its just me or there is a problem, I know this my sound stupid, obviously the power that I would feel with a low fuel tank is more than what I would feel with a full or close to that, but this does not mean that it makes alooot of difference, which I think I am feeling now, so I would appreciat it if you guyz could advise me as I am really getting disappointed.

You shouldn't really feel any difference between a full tank of gas, 1/2 tank, or even a low tank. More placebo in my mind.
If you're really feeling a power loss then it could be:
1. Water pump out (happens on E55's), fixed under warranty
2. Maybe you're affected by the same ECU flash as the E55's
3. Supercharger clutch not engaging for some other reason (besides #1 above due to high temps)
Definitely take it in and have them look for the pump issue.
Cheers,
Darren

Go and purchase a scan tool. You can do a search in this forum. Check for the IAT. Most likely you have a bad pump. If you change the pump and still experience the same problem, then the service technician didnt flush the system properly.
