The fuel trim was looked at before and after removal of the plastic tube. Keeping the plastic tube out does throw it off quite a bit if I remember but putting the plastic tube back in puts it back to basically what it was before.But most cold air intakes require a tune right?
While the car can make adjustments, I’d imagine that if we are changing air flow enough to gain 18HP, the trims are worth looking at.
