For the check engine light, yes.

For fueling, meh. You could make a touch more power with a tune.

Tough truck entry?

will the check engine light make a limp mode? or will I still be able to get to highway speed?

No limp mode for an under performing cat. Just make sure the upstream o2 sensor remains in place and at least 16" from the open end of the hater pipe.
