Is it even turning on when RPM delta is positive?

-5 was the timing lol delta was later set at -17 which is oem wrx. but i removed that too

I meant to say why is the overrun delta rpm setting doing anything when set to positive number. I'll leave mine at the default off setting.

just my thoughts dude

but im not sure how many people enjoy rich a/f mixtures just to make cool sounds. just save for replacement cats and o2 sensors and then you will be ready to rip up the touge

at least know what you're talking about before posting.. super rich a/f mixtures?? I'm still seeing stoichiometric (14.7) numbers even while at 5k+. it's not like it's dumping full throttle amounts of fuel..
