TARGET AFR with 17psi boost at 8800RPM?
Ive been reading all the AFR threads almost for a couple of hours...
Last weekend finally i change my injectors (60s) and all become clear....
Now im planning to get my AFR on the spot this large weekend...
So the question..., 8650rpm, almost 17psi of boost, at open sea... all the times i saw the rpm going to 9000 or 9500 on the air while im at WOT on open sea...
My Target AFR will be...... 11.7 ?....or

You may want to go maybe a little richer, just to be safe.
I am sure someone with more experience will post up what would be safe.

I know i may be an exception but the stock pistons are forged just like the aftermarket ones so what actually makes them weaker?? Won't any piston have issues if you run it lean/hot?

I run rich like this on stock pistons. You can run CP, RIVA leaner and not damage them. Just a little detonation and you will more than likely blow a headgasket, too.
They are all forged, yes. But they are not all made from the same type of aluminum. So the OEM stock pistons are weaker than CP, RIVA, etc.
Also, some reason Eric your ski is slower. I don't know if its the ecu flash you have or what. Maybe your timing on your ecu is lower than mine.
