f6 hunting at top end

[Orangeback]

Hello 

 Im a new f6 owner and I've got a dyno tunes 2012 f6 with 379 rwkw , it is hunitng for power at top end, could this be a coil breaking down?  , or is it an injector thing ?, or valve ? fuel pump delivery?

I am unsure of any of the modes to car ,

believed it was to be stock with remap tune, but unsure, 

as the tune shop had no records to what they had done other than the dyno sheet.  any suggestions to why ? 

 thanks in advance

Well, it won't have made 379kW with a stock remap tune only, so there's definitely some other mods on the car.

 

It could be the coils or spark plugs. They're the easiest things to check.

It could also be the oxygen sensor. Another simple thing to check

 

Contact the tuner of the car and get them to look at it, as a simple resort, after you've checked the above basic things. If they were able to tune it, they should be able to diagnose it reasonably quickly.

Yes.

Probably is.

Definitely not going to affect top end power.

Couldn't have said it better.

Bunch of slackers that don't keep records? Maybe they didn't modify it and they just tuned it?

 

Just chuck in a new set of gas plugs so yer gap is right and if that doesn't fix it then swap out the coils for a genuine set.
