Help with my KA-T

[myRed240]

So I've officially been turbo'd for about 2 weeks now. Not knowing what to expect, I've taken relatively easy on my car, e.g. I haven't done any WOT runs yet.

I've been having trouble with my fuel delivery and fouling my plugs. I do have a wideband so I'm able to monitor my a/f's. At idle I get anywhere from 14.7 to 17 and while cruising it fluctuates between 13-15.5. At mid throttle (accelerating) it might see 12's.

Last week I replaced my plugs because my idle sounded like it was missing a beat every 10-20 secs once it warmed up. Also, when going up hill at low throttle, my car has died on several occasions. Once the new plugs were in, it idled perfectly and ran smooth. Until yesterday. The idle started to act up again and I stalled at low throttle: uphill/flat/downhill.

Today it was even worse. I was low throttle going up hill and it just died. Usually I can start it back up, but when I tried it wouldn't start. Instead I got some smoke from engine bay (don't know where from)and had to wait ~10 minutes to start it up. It sounded fine, but I haven't inspected it yet (at school right now).

Almost same setup for me. I have enthalpy tune with 555cc and z32mafs. My guess is there is a boost leak somewhere....Checked your car's timing?

Can my timing be off if I've never messed with it? I do feel like I have a boost leak, but finding it has proven difficult so far. I'll look more into that possibility.

Thanks!
