S430 feels slower?
Yesterday I took her for a little drive. I thought I felt that the car didn't pull as hard as several weeks back from a standstill.
Just to make sure, I nailed her right up to 5500 rpms. Yup, didn't really pull as hard as before.
It could be that I'm just feeling things, but just to make sure, what would I check for that could cause the motor to lag? Oil and oil level is fine. Oil filter was changed 3000 miles ago. I don't really know what else would cause it to be so sluggish.

Just got back from another run. This one guy in a retarded Honda CRV kept taunting me and my buddy in the passenger seat. He threw it into neutral and revved it. Ate him for lunch.
And also, I always make sure the car is fully warmed up for full throttle driving (which I occasionally do).
Air filters - fine
Oil - fine
Oil level - fine

Someone on another forum said it might just be me getting too much used to the power.

As for ECU upgrade, I'd skip that altogether and save up for a Kleeman blower. I'm tired of its slowness.

Well, ebay doesn't have any...so I have to order from the stealership or what?
MAF sounds a good bet, assuming I'm not feeling things, my mpg is also poor. But I have no idling problems or whatsoever yet.
