I wish to offer the following for your consideration. This is with sincerity and genuine concern for your 'Stang and your wallet.
* Generally speaking, when a fellow enthusiast is unfamiliar with how to use a tuner for
very basic PCM/ECM adjustments such as the RPM limit, my general response is that you need to take it to a tuner who knows what they're doing.
* Based on the overall context of your original post, I'm guessing you are suffering from a lack of traction on street tires when you go to the track. This can and will happen even with an otherwise unmolested S197. This is exacerbated with a manual transmission, because they are just inherently harder to drive.
* So I'm assuming you need an RPM
launch limiter - because you are experiencing wheelspin when the light turns green - and not a tune that increases your redline.
* What I believe you are describing above is that your tuner - whatever handheld tuner you have - can adjust the
idle RPM and /or the actual RPM redline. Neither one of these adjustments will help you with traction control.

My suggestions:
1) Get yourself a set of 15" drag radials (and wheels) that you can swap out with your street tires when you go to the track. This is the best way you can improve your 60 ft times.
2) Get a two-step. They are super simple to install and you can easily adjust your launch-limit RPM where you can stand full throttle on the gas pedal to the point where you
won't break traction once you pop the clutch - no matter what tire you are running. You should be able to dial this launch point in after a dozen or so passes at your local track!!!
PS: For your reading pleasure, there is no such thing as too much power. There is only such thing as too little traction!
PSS: More info about your mods, if any, would be helpful!
GOOD LUCK!!!
