what kind of power increase of a Tune on a stock GT/Auto without a CAI? Is it a bad idea to NOT install a CAI/

I was told about 12-15 rwhp less!

I did it... Remember, the performance tunes that are preloaded are made for stock airbox, if you did install a CAI you would need a tune for that.

Of course most tuners come with pre-installed adjustments for the addition of a CAI, but you get my point... The tunes are made for stock boxes.

Anyways, the tunes DEFINATELY helped me with a stock box... Car ran 'crisper', less sluggish feeling, and the exhaust sound is cleaned up immensely and sounds great.

You have two choices... Get a universal tuner now and then later get a CAI and use the universal tuner's pre-installed CAI add-ins, or you can get a tuner+CAI now and have them be made for each other... In the end that is the better choice if you decide youll get a CAI later.

If you're not getting one later, then the performance octane tunes will work great with your stock box.

Either way get the tuner from B amachips or Brenspeed. You will get much better performance with these tunes than the "canned" tunes that are preloaded into the tuners.
