Best CA smog-legal tune?
Any recommendations on the best CA smog-legal tune for our cars? I currently have EC, but I have to keep flashing back to stock when I go in for a smog check. After an ecu scare this year, I'd like to just tune it and not mess with it (after a recommendation from another member whose name I don't recall, apologies).

Do you have cat deletes? Otherwise I can’t see a tune making you fail emission, unless the tuners are shutting off secondary o2 monitors for some reason?

Technically none are smog legal as none are certified, but any should go through smog if you have cats and the tune is not turning off the 02 monitors, my last EC tune had the monitors all active as I was stock and would go through any OBD checks.

I have a few oe files that keep all emissions system on including race gas files.
I'm sure any tuner can give you what you are looking for. I think the car runs better with them on. Throttle feels a little more sharper.

any tuner should be able to provide you the same tune with or without cat deletes.
ask for an updated EC tune. generally speaking, modifications to engine computers of any kind is not legal.

As you guys have said, Jerry replied that it won't pass if catless but should pass if catted. I guess I'll stick with my V5 and cross my fingers. Thanks, all.

You're wrong. The Weistec Stage 1 tune has CARB EO# D-691-3, meaning that it's smog legal for use in CA. Not many tuning companies go through the process of getting their tune smog legal.

Good to know, I knew they had a carb legal blower setup, didn't realize they certified a standalone tune, so guess there is one option then that is smog legal.

Just passed California smog following Renntech HHT tune on my G500 (m113 5.0) =)
Only other mods were K&N air filters, deleting middle muffler, and upgrading to Magnaflow mufflers after cats. No warning lights after tune. I was scanning this post prior to going in for a smog check, and decided not to flash it back to stock prior to the check, so wanted to follow up.

for those interested all of my tunes are sold with emissions intact.
