Default 3inch turboback exhaust clip/AFR idle readings with revs and some death

Okay guys...heres the vid...sadly it is in black and white...but you get the idea...keep the volume somewhat LOW because once i start talking my voice is kind of loud..sorry. Enjoy. Let me know what you think.

New 3inch piping from turbo back, to a HKS Hi Flow 4.5 inch outlet. Also, check out the AFR readings and car temp and rpms. Notice the smoke from the exhaust?? it aint cold outside..im not sure if thats rich or lean..i think rich.

UPDATE AFR VIDEO ON PAGE 3

that little bit of smoke is just from the rich condition caused from the bov opening and being vented to atmosphere same with the boggin/stalling..but im trying to figure out why its staying as rich as it was at idle for that long...

BUT once we can get you back down for another day/weekend, we will set you up with a blow through, readjust the safc and you will be boosting and reving as much as you want with no stalling..

and the exhaust sounds great, cant wait to have you back down so we can get it set and get some action videos

Since the vid didn't show you running under load it's hard to say. What kind of readings to you usually get driving around?

You can drive it as long as you're not pulling super-low o2 killing afr readings. It'll cost you your plugs but it'll get you to work and back.

when we took his car out for the first drive, keeping it out of boost, it was reading from mid 13's to 15.3 while cruising, which is dead on to what my car was depending on throttle%. The couple times it started to make boost, it would drop to low 11's up to 4psi, then jump to 14's after 4psi and throttle was cut immediately. But I have a feeling that is due to the FP ECU still being in tact and the stock pump just not keeping up once positive pressure is built.

All the factory o2's remained in place, except the factory 3rd o2 that was on the midpipe was not connected during the initial drive. but Carlos did say that he had a CEL before we even started the swap, so if its still present when he comes back down for the finishing touches, Im gonna run a diagnostic on it and see what the CEL is for.

Just a little more tweaking on the weekend of the 6th, and all the bugs will be worked out.
