I want to use a SCT iTsx tuner with my iPad or iPhone 5 and my 96 SVT Cobra. My concern is because the 96 has a mechanical speedo I wasn't sure if the performance tests would work, IE: 0-60, 1/4 mile etc. I called SCT a few months ago they said yes. Vim ready to pull the plug so I called on Friday to make sure, the tech told me the iTsx won't flash my ECM and I should buy the basic hand held tuner. Has anyone used the iTsx with a 96 Mustang? Thanks, Spiney-Dave
