Wide open throttle

[Ock]

This is my 1st s550 - its a gt w/a10. When driving with wot @ about 80-85 it "feels" like i am not accelerating anymore so i let off so i don't damage it. No bad sounds, acceleration up to that point is good. Sometimes a slight rattle around 2-3krpm. This is with all traction control on. It just doesn't feel right. Ive had multiple 5spd's that obviously didn't do this, all 99 and older so it didn't have all the safety features. It is quite possible i am crazy and its fine, but i don't want to damage it. It only has 12k miles, i bought it @11,600 miles.
I have an appointment since i have original warranty left and the extended i bought, but if its a non-issue i don't wanna take it to dealer. It's relatively unscratched and in good shape.

Sorry if this is just a crazy rant in advance...

It’s an issue. That thing should roll up to 140mph no problem. Without and hiccups or hesitation.

You are using 93 oct ?

Tom that car should be pulling strong at 80-85. WOT at those speeds should have that car's engine screaming/shifting hard pushing you back into seat holding on till 140mph. Mine does. I use nothing but 93 octane but it shouldn't matter much.

Have you tried Sport or Track mode?

Could be a my key issue (speed limiting)if it only does it with one fob. Check both fobs. Hope you get it straightened out. Cheers

Yes - it was same. I think i need to try it again to make sure - but if just accelerating somewhat normally this shouldnt matter right? its just the trac control to keep from spinning out?

Odd - i wonder if there is way to tell. ill try my other key.

It feels like i hit a rev limiter but its not that. it just doesnt feel right. Up to that point it does put me in seat - it feels great. No ticks,taps or craps... its so odd.

Are you sure you’re not using a key fob that was programmed as a valet or nanny key?

Have you tried driving it with the Trans mode being in “Sport” and WOTing it? The car should be pinning you to your seat if attempting a blast run from 80mph…

I honestly don't know about the fob - it came w/2 and i just started using one. Is there a way to tell on the fob? As for sport i usually drive in this, and it still does it. On gear selector i haven't really messed w/S.

How about doing a hard reset. Disconnect the battery on a weekend when you aren't going to drive it. Also, as crazy as it sounds, put fresh batteries in the fobs.
