2010redGT

I bought a 2010 GT late last year. After buying it, I looked under the hood and under the car. I noticed BBK LTH running to a BBK off-road X-pipe which led to Flowmaster Series 40 mufflers (42443). I love the sound. I haven't been able to locate any other mods so far. The car runs great overall. Just a very mild hunt for idle in drive, plus or minus 200rpm. In park, perfectly smooth idle. Does a a mild exhaust aroma when sitting still. To be expected.

This car would have a tune to even run right, bypassing the rear 02 sensors, etc. etc. Is there a way to determine exactly the settings the tune might have. I guess I will have to buy a tuner. I will probably get a CAI too.

There is a local speed shop that does dyno custom tunes. When you get this service, do you have to buy one of their tuners?
How much on average does a dyno tune cost (without the tuner) ?

You need to find out what brand tuners the local shop supports, most support more than 1 type, but they may have a preference so check with them if you plan to use them.
