Default Need Some Help

Exhaust smell is strong, kinda toxic. Where do I begin? My a/f at idle is 13.6-14.1 range. Normal acceleration 12.8-13.2 and semi fast not getting to any boost a/f is 14.2-14.6 range. Car bucks at 1600rpm to 2000rpm and normal accel. also. Just dont know what to do where to start. Talked to the shop that tuned it last and was told my o2's r probably bad. The thing is I have no engine codes. Any info please.

Do you have a wideband? You talk about boost, are you going to use a MAF or a custom OS? If you run WOT at 14.2 to 14.6 you will have problems fast. It should be 12.5 or so under boost.

Can you post a run log and tune?

Are your injectors scaled properly? 60s can present some tuning problems.
