Default Do I need to Tune if i change plugs?

I plan on changing from NGK TR55's to the NGK TR6. Do i need to have it retuned for this application?

So you're just replacing your spark plugs, and you're asking if now you need
to get a dyno tune done on the car. If that correct, what you're asking?

If that is correct, why would you need a tune if you're only putting new plugs in it? Think about it, does every place that does tune-up, dyno a car after.

Just because you're switching to a different plug doesn't mean it needs a tune.

dont be a dick. its just a question.

no you dont need a tune, just make sure you have them gaped properly, if you already have a tuner, just ask hm what the gap should be on your setup. when i put my plugs in (tr55) i left them at the stock gap which is .55. I dont have a tune right now on my car other then factory and im not having any issues.

Thank you. I was pretty sure that I wouldn't need a tune, but I was reading a thread on here about a guy who changed his plugs and it ran crappy because he didn't get a tune, meanwhile he probably just didn't gap them right. I'm probably gonna gap the TR6's at .035 since it's not recommended for them to be gapped much differently, and the car has a decent amount of power behind it.

Thanks again

sounds good. yeah i left mine at the stock gap, so i would say maybe leave em alone or follow what others do with similar mods as yours.
