SCT adjustments

[Mustang Pete]

I just tuned a my stock 4.0 automatic to run on 93+ Octane. I removed the speed limiter and lowered both low and high fan settings.

I notice my shift settings are on the high side and hits the red line each gear as it shifts.

I haven't changed over to a CAI or dual exhaust yet. But I was wondering what is the sweet spot for each shift setting so I can get the most out of it when I step on it. Any suggestions would be very helpful. Also, I notice she idles a little faster. Not sure if that is normal... and what idle setting should I have to be smoother?

change the WOT shift point down about 100-200 rpms. I love bumping the WOT shift pressure too. mine locks the belts
you most likely won't notice a difference between the 87 and 93 octane tunes, especially with being stock...just a suggestion if you don't want to spend a lot on gas. Also, your idle should probably be down around 750rpms
