So when I take my car, 09, to redline WOT it has good pull and power till about 6500 and then it seems to plateau for just a little bit then the power comes back. From what I searched and read it could be plugs maybe but seems those impacted the whole upper and or lower range. Car has 16K on it. Its not critical but thought I would ask. I am sorry if this has been covered a bunch and please point it out if it already is. Not really sure what to search...

Oops. I found it. Hiccup at 5k RPM, loss of power at 6k plus, dealership CAT is fine
Seems that it is most likely ignition related. I will research it. I know fold said 20K is the life and I am close, plus I have no idea what kind of driver had it the first 15K. After more reading, gonna check the ignition, cat, and I noticed the battery had some corrosion dust so will clean that up too. I will report my finding in case someone uses this thread one day.
Yeah I will followup on the plugs. Thanks for the help. Kinda blunt on the whole signature thing there buddy but sure if I get around to it.. Thanks
Since when has "please" been "blunt", the reason I suggest it is it helps those of whom you ask for help to interpret what you are asking, and it kinda speeds up the process, like your RX-8's year and transmission type in a Sig.
Any internet forum can only advise, correct diagnosis is not always easy, IMO it is always easier to start looking at what is common rather what could be a remote or less known issue, in so many things it is better and easier to start at the source (ignition) and work back...Yes it "could" be Fuel Pump related, however, I seriously doubt that as the FP in S2's is a later improved generation and is not know to give any issues for S2's like in Series 1's...it is only <3 years old.
Also didn't realize why the signature was important until I read other peoples and makes sense. Thanks for the help and suggestions on this. It seems to be fixed for now but I will reference this in the future if needed.
Is there a different path the intake air could be by passed, I have always got that same feeling around that rpm, and it feels like a kind of ajustement the engine makes to be able to reach the higher rpm range
My engine has always plateaued a bit around 6500-7000rpm. It feels like it's about to run out of air, and then it doesn't. My understanding is this lag is caused by waiting for the third set of intake ports to open.
