MM tune with CAT
I just took the plunge and bought an AP due to the discontinuation. I wanted to see if other people have run a stock cat or RP supercat with a MM tune? I am buying a midpipe for when I go on the track, but don't think I want to deal with fumes on a daily basis. I was thinking of either keeping my stock cat or buying a RP supercat for daily driving. Before I did this though I wanted to see if people had experience of cat life with a MM tune. Thanks.

I have the RP cat and it's a pretty good item when paired with MM's tuning.
My last RP lasted about 11,000 miles but it's demise was caused by the ginormous speed bump at MNAO's headquarters. (I put a nice big dent in the cat which most likely broke the cat material)
I had RP repair the cat for me last year and so far it's holding up quite nicely despite the leaner AFR's.

well, on OEM maps I was EASILY pegging the wideband at 11 AFR at WOT around 4k.
I'm closer to 13's at this point. Probably somewhere in the 12.8 - 13.2 at wot.

IIRC from when i looked at the tables on OEM map, ~30% or more of the total range had a target AFR well below 11. i think there were places where the target value was in the low 9's

^^ I agree but without an aftermarket gauge, all I see on my graphs is 11.
I'm pretty sure it was well below that as you mentioned.

correct.
till I decide to go for max powah, the stock wideband will have to do.
