Wondering if anyone has a stock cat I could buy?
I just sold mine over the summer unfortunately haha.

I am running lean with my Vortech so I think swapping out my test pipe should help with that a little bit.

it's only going to richen you up about half a point what are your afr's at in open loop?

WOT they are at like 14-14.5 or so.
Well right now they max out my AEM wideband gauge lean so something is obviously wrong.
Was running great at first just a little bit lean at around the 14 mark but then changed to super lean and bogging down on my drive home when in full boost. 1-2 psi and no issues but upper in the rpm range it goes super lean and makes no power so obviously have been keeping it out of boost now.
If a cat can take me from like 14.5 or so to high 13's would feel much safer to me.

TelosHedge

high 13's are still too lean for a basically untuned setup. you should be somewhere in the low 12s, and possibly even richer as you get closer to redline.

ditch the fmu and go with some sort of management. it's worth the cash, take it from me

Yeah would love to have it be richer. Going over to Jeff's tomorrow to see why it is running so lean so hopefully all will be good with it.
I do definitely want to get an AEM EMS but that won't be until the summer most likely.
If need be and as a band aid fix I can get a vafc to add a little fuel right? I know others that have done that and has worked out well on stock boost for them.
