I'm sorry to hear about the issues you're having with your Tune. We send out thousands of tunes and build them all from the ground up for your PCM code and your mods. They're not just "canned" tunes, they're built custom by our team, so every once in a while it's possible we mess one up! We'll definitely get it straightened out for you, though if this is the case! Give one of our Bama Tuning Specialists a call and they'll work with you to figure out exactly what's going on.
Our Bama Performance tuning specialists are here in the building Monday-Friday from 9AM-5:30PM EST and Saturday 9AM-5:30PM EST
