I atribute the 10/10 loss with the 3 way cat and 2 inch cat back...as before with no cat and 2.5 inch stright pipe, it was 10/10 more.
First three runs are on stock boost. 4th on 15 PSI. 5th...the one we lost, was also on 15 PSI. 6th run...ha...like I said, since it was lean, we didnt run a 6th time.
Ok, food and pack the car up...im tired too.

and dude. WAY Too lean....you should be in the 11's for AFR ?!?!?!?!
I think around 12-13 PSI is where the injectors will his 100%....seems weird that subaru would fuel cut at that PSI doesn't it
your stock boost is just about what my friend found today, when he threw the wideband on his car...it was real good...but that was 8 PSI of boost...anymore and it's gonna get intersting...he's also running catless exhaust, cone filter, and intercooler

However...if i pump it up another 1~2 psi...it will fuel cut...the REAL cut...as in, no fuel until boost comes back down.
I did tune it back down %4...which is about 1.5 PSI lower.

I'd be quaking in my boots with an air/fuel ratio like your 15psi run. Thank for showing that info. I know what I won't be trying to do. Your stock air/fuel ratio mirrors my last dyno run air/fuel ratio exactly. Interesting!

I've always assumed that no ping = go for it! I guess I'm going to have a melted piston one of these days....
I have no idea what my AF's/EGT's are - I really need to get a gague installed... but my sparkplugs were white when I changed them out...

that was NOT ping. that was the fuel cut gremlin. notice how it goes FULL lean when it cuts?

Ping is detonation or preignition....
Lean is just that.....lean....it'lls run way hot and melt pistons....after a long pull you might ping ...

Did you take the dyno run pics down already? Dang, I'm trying to reread, re-compare, re-note some info about your runs and they aren't coming up. Just trying to be sure it's not my internet connection.
