So I asked a question to the SCT's customer support after reading their tune could give a 28hp & 34tq boost. I asked, quote "Are these numbers accurate for a stock mustang? As in, if i were running premium fuel, hitting the 420\390 stock numbers, i can hit 448\424? If not, what is the top numbers I can hit stock?" And received an answer quote "Those numbers are the results we got when testing on our dyno, there is a number of reasons that you might get different results then we did. While it’s the same tune that we used you might have different environmental conditions that would affect performance. In short you should get around our numbers but it might be more or less then what we got." So this really didn't answer my question strongly enough, kind of vague. So I asked again, quote "So you were hitting around 448/424, or close to those numbers in your dyno tests then?" He responded with "Right." I then asked for a link to a dyno sheet and he said "We don’t have them available for publishing, I actually don’t think we have the data anymore." Anyone have any first hand experience or thoughts on this regarding a 13-14 stang with the SCT tuners?
