Las Vegas tuner?

I think the most important thing to do first is read the diagnostic code and see what is the problem it reports. Depending on what it is, you can decide on how to handle it. If you decide on the tuning route, a bit of info on e-tuning :


An eTune is a pretty great service. First, you have to decide whether you want to go with UpRev or ECUtek for your tuning needs, if you search a bit in the tuning forum you'll find a bunch of threads comparing/contrasting the two.

Once you've decided, look for a reliable tuner that does etunes, we have a few here on the forums. Then, the tuning software you've decided one will come with a OBD-USB interface cable that you will use to flash tunes and data log. With the cable hooked up to a laptop you go for some drives and log data, the tuner will tell you more specifically what they need. (for example, third gear pull, city driving, high way cruising) With that information and some input from you, they go dialing in a custom tune. Most of the times it'll take a couple revisions to get it dialed in, but the flash process on your end is simple. They send you an email with the tune file attached, you use the obd-usb interface to flash it onto the ECU.

As an added benefit to the tune, they can also remove a specific DTC if it is in conflict with a modification. People with test pipes / HFCs may get the post-cat O2 sensor code deleted, for example.

Now, from my understanding what you want is to have that specific CEL code removed due to modifications. The price of the tuning route may seem ridiculous for simply bypassing a CEL.
But the benefits are much greater than that alone. A good tune will make the car feel like a different beast. One of the best mods imo, and after a healthy amount of bolt-ons most people here will recommend a tune.
