LTs will almost certainly throw a CEL over time, and a tune is needed to correct that.

That said, we have had guys run LTs without a tune for quite awhile with the CEL on without issue. Car still runs great, its just that the rear 02 sensors are sniffing more emissions, but I don't think the rear 02s will make any adjustments to the A/F ratio. I think that is done via the front 02 sensors.

But a tune is still a good idea of course.
