When do you need a tune?

[NJ2002WS.6]

Ok, I am kind of new at all of this. I just want to know what a tune is for, when should you get one, and what are the performance results??
I just have a Corsa and a lid.

Well tuning you could do at anytime, depending on who good the dyno people are is how much you can expect but it will make a difference. Usually the more time it spends on the dyno the better results you get. But it is a good idea to have it tuned after getting some bigger mods installed. If you plan on getting cammed or heads ect. ect. then wait for the tune if not go ahead and get it done.
Hope that helps you

a cat back and lid wouldn't benefit from a tune-that would be 400 bucks ill spent. major "air flow" mods like porting the throttle body/ mass air flow, getting a new intake or adding full exhaust components like headers/ y-pipe to your existing set up would definately benefit from [if not require] a tune.

thats basically what i was going to say.
if u decide to go with mods such as a cam/heads you're going to want to get it tuned, the car will need tuning then because your computer wont be set up to run with those mods, and it will need to be programed ie...tuned

I just have basic bolt-ons and I was fine until I did the headers. After that my gas mileage went in the toilet. I keep putting it off because I kept thinking I was going to do a cam or something, that hasn’t' happened and it's two years later. Keep putting it off because it's a garage queen, net spring she's going on the dyno.
