So, my buddy's car is on the way to a very reputable (top 5 shop) and he found out they dont intend to tune his car with widebands (stock intake, stock pulley, longtube headers and tune only going forth).

I know Jannetty installs a wideband for tuning purposes pre-cat.

Is tuning via the OEM non-wideband cats a good idea? Seems odd. They also said they could add a wideband but it would be after the cat, which seems like it would throw off the readings.
