Next month going to get my 03 tuned and how a few questions.

Since I have an 03 and no wideband, will they have to add one to get my air/fuel in, I have an extra O2 bun welded in my test pipes, maybe they can use that?

What is everyone experience with throttle response, did the tune help out at all?

Thanks for any help.

 

Yes, it helps out a lot. That's the first thing that you'll notice is that the throttle response is much smoother and the car will be smoother at idle.

 

If you're getting tuned at a shop they'll either use that bung or use an exhaust sniffer, or both
