Hello guys, and gals. Have a question maybe someone can answer. Im the second owner of a 2007 Mustang GT the prior owner installed a JOT CAI, 62mm throttle body, steeda underdrive pulleys, and bassani cat back exhaust. Now being that Im the second owner,and wasn't given the prior owners contact info (due to privacy laws) how do I know if this vehicle was tuned properly

If you have a JLT CAI and it isn't tuned your car will go into limp mode and the check engine light will come on.

Yep, and without the original tuner, your stock tune is lost.
This is why you should not buy a heavily modified S197
without being given the tuner with it as well.
The tuner is locked to your VIN # so its no use
without being with the S197 it has tuned.
Not only do you need to know if it has a tune
but what tune is currently loaded...
What octane fuel are you running?
You might have one of three tunes.
87, 89 and a 91 octane tune...

Well no check engine light so Im assuming it is tuned properly,however the throttle body spacer causes the cone of the CAI to damage the underside of the hood when its closed. So a trip to brenspeed to get a new CAI and a few other goodies is fast approaching.

And ditch the problem causing TB spacer all in one final swoop...

I always wondered what TB spacers were for... Underhood damage...
