The key is to ensure the tuner is unlocked. To do so you'll need to return the other car to the stock calibration. The tunes on there won't work but you can easily get some that will.
That's BS. JLT has a composite one bigger than yours :hihi:Tunable Induction can help you...all the way.
Tunable Induction has the coolest flowing, largest MAF housing (95mm) available for '05-'09 GT's
They are a good choice and so is Brenspeed.com. I think Brenspeed's package is $25 cheaper. You really don't need the three Octanes unless you are going to run all three. I opted for the $75 single tune from Brenspeed.Ok. So after I set the other car to stock, should I go to like americanmuscle.com and purchase the 3 custom tunes?
