Is my tuner locked to the shop that sold it to me?
I purchased my SCT X4 tuner for my 2005 mustang when I let a local speed shop install long tube headers, CAI, and high flow cats. That was about 4-5 years ago. I have not messed with the SCT since then. I just installed 4:10 gears and went to adjust for them in my tuner like I've seen online...- 91mini
