thanks for the reply, I am soo glad that you were so helpful...btw, if it was coils or even plugs, wouldnt the graph have more spikes and drops? Check the wastegate...at the end of the rpm band most start to open up and may just purge most air out...on the srt's we had the same problem with the waste gates opening up at the end, but there was no spike...I would go from 19ish to 11ish by the end

Redlined RX8

I'm running stock plugs. I still the same ones that came with the car. I have just under 15K miles on the car so I was hoping to wait until next spring to replace them. I usually put the car away from November\December until spring unless there is a warm day or two in between.

It's recommended to use colder plugs for FI. I got these:

4 trailing plugs are needed and they come with shims to work. they are rx7 plugs. also the BHR coils are promising as I got those on order. I bet this will help you with that dip at 7500 RPM and your numbers will go up
