Im looking for just a stock firmware file for the sct x3 3015 tuner. Sct does not have the files for download no more on there website. I bricked mine putting firmware 3000 instead of the 3015. Also my car is 1999 v6 mustang and after I have took of the stock canned tune from the car it wants to jerk here and there but with tune it runs fine. My email is staleyw7@gmail.com thanks
