So my car has a green filter,depo catless downpipe(just installed today),symposer delete,boomba BOV, and custom magnaflow catback. couple questions

1) In the settings for the tuner under options do i check CAI and CBE? I have no CAT though.I didnt see an option for a catless downpipe. Or a different setting? Is there a certain setting to achieve the turbo whistle?

2) All these videos of the turbo whistle is what Im going for. Mine still dont whistle! would I have to delete the magnaflow muffler and essentially run straight pipe to get the sound?

3)Does the sct automatically turn off the downstream o2 sensor?

thanks in advance!!!

In order for you to do any of that stuff u need a pro tune. The sct x4 is loaded with very conservative tunes and can disable features like o2 etc

Actually have a custom tune made for ur mods in other words. No tuner whether its sct cobb livernois will have any way to disable or add features without a custom tune
