Is this worth tuning...

Did it throw any errors without tune ?

Surprisingly no, OTR was on for 3 days before I had it tuned

can take a while some times to report the errors, but usually if it goes outside a preset amount of airflow per map/throttle value it will throw code eventually or if ur within that it may not at all, but u would want it to as it means u have made decent airflow changes

Even when I got headers changed from stock to 1 3/4 long tube .. I had it tuned previously before new headers and once new headers got Installed I was expecting engine light to come on. After driving for a little over a week before it got tuned again it still didn't throw a code

usually tuner will go in and max out the tables that cause the error codes, then disable cat efficiency, rear 02's cell and few others straight away so then u wont get any codes in future from mods, i had a intake on mine was fine for many months and then got full exhaust extractors to mufflers and even without a tune took 4 weeks to throw the code
