So i was wondering if a tune would benefit any power gains if my only mods are cold air and exhaust?

 

definitely.
tunes will make power gains even if your car is stock.
recommend it too, prob the best bang for your buck

go to trifecta performance for the best one

Now I'm not 100% positive, I would like to know also. But It's my guess that it wouldn't be that much over what the mods already add. And it doesn't seem worthwhile to me. I mean you would have to pay for the tune. I would wait till you get a bigger mod, such as dropping the pulley and getting better fuel Injectors (just an example). So you'll get the most from your money when you have to pay for your tune. Unless you own HP-Tuners or something.

 

Agreed with this.

You will gain some power from just tuning it stock, but it's only worth it if you have HPT or a friend with the box who will retune you for free/cheap. Trifecta is not a good idea if you're bone stock since you'll have to pay the full fee again when you get new parts. For that much money you could pretty much buy your own box.

 

Trifecta does NOT have the best tunes for the LSJ. Find a good tuner that uses HP Tuners and you'll be MORE than satisfied by the difference your car will have!
