Have you tried datalogging while making a pull?

 

[Broken-Code]

Yes i did, some knocking activities appeared

very vague,

who is tuning the car?

have you been datalogging, what's the fuel system like, etc...

It's the tune. I had the same problem myself. Had it retuned somewhere else and everything was perfect

Knocking will retard the spark, which will reduce power. You took down the graphs, but I'm guessing tune related also.

What's the plugs gapped at? And what kind of boost are you making?

 

[AGITATED]

No graph to view and not nearly enough information but clutch slip, if a manual, can make a graph wavy, so can several other things....

Do you have a boost gauge to actually see 9 or are you assuming that? What's the MAF orientation?
