I was simply going to change the stock filter to a K&N. I've used them on all my vehicles for years. Obviously there is no tune required when doing this, however, there is a need for a tune when using a CAI? Why? What is involved in "tuning"?

I've modified the airbox on some older vehicles to mimick a CAI. Can that be done on a 2006 GT and if so, is a tune still required?

 

A tune adjusts the car for the increase in airflow and prevents running lean (too much air to gas)

 

you will get much more performance out of a CAI/tune combo

 

That too

 

so how is a tune done and whats the cost?

 

I got my JLT CAI/Tune combo from AM for $529 plus free shipping. They custom write a tune for you depending on what you want (ecomony/performance) and what you have (mods). It's loaded onto a handheld tuner which is plugged into the car (there's a outlet thing under the dash on the driver's side). You upload the tune and youre good to go. It's very easy.

The tune completely livens up the car. Better shift points, better throttle response etc

 

IMO these cars will run better with a tune from the get go. I think a lot of whats going on is vendors have found a way to package in CAI's with a tune. I imagine if you took a 4.6 and dyno'd it with a cold air intake, then took that intake off and dyno'd it again but with a tune, and added the amount of power gained from both, you wouldn't be much behind what they would dyno at together.

Not saying a CAI isn't worth it, but I do think a lot of it is based off of sales mentality.

 

$530 is a little steep. I'll likely just go with an axle back exhaust, K&N, and I still need to tint the windows so a tune is not that important right now.

 

You can always just buy a handheld tuner with a tune. It's just a better deal buying a combo if you're interested.

Just checked AM, a handheld with 3 custom tunes is $379

 

Does the $530 include the handheld tuner or is that just intake and tune files? If it's $530 for everything thats a great deal.
