Product Reviews

One of the best mods I've done for the '13 GT Track Pack. Literally feels like a brand new car - can't wait to take it to the track!

The SCT X4 tuner is a solid product! Really happy with it and the customer service has been great. The main thing I love is the ability to update the firmware over wifi rather than plugging it into the computer each time!

Guys, do yourselves a favor and order this tuner - especially if you're stock and plan on adding other mods in the future. Steeda loads your custom tunes on the tuner before they ship it out to you, so you're ready to go once you get it.

One of the best features over the X3 is the ability to use wifi to update the software - no more fiddling with plugging it into the computer! Thanks Steeda

Also picked up the Steeda cold air intake with this and let me tell you, the car feels like a beast. It chirps going into third and runs great!

After installing this tuner, the car felt like a night and day difference. Can't wait to get it on the dyno!
