Can I run without a tune?

[Deleted member 10795]

I have a mst v2 intake installed, I have a catless downpipe ready to install as well as a charge pipe, was wondering if I can run these without a tune? Im going to use a JB4 and custom map in a couple months once I get my full exhaust, for the meantime can I run like this?

Intake doesn't need a tune. Catless will most likely throw a CEL eventually and not have big benefits until tuned.

Yes I dont mind the big benefits till tune, I just wana make sure I wont have any actual problems besides the CEL

You can run without a tune; the Check engine light is triggered from the downpipe but it's only a warning light.
