know how to tweak an SCT custom tune ???
I have a 98 Cobra with an SCT X3 handheld # 3000.
It has a custom tune on it, which I want to tweak a little bit further.
I can easily do this with my Jeep's Predator with a custom tune on it.
The car/tune is close, I just want to adjust the timing a little and the fuel curve.
any hints, or HOW to's ??????07 SRT8 Jeep. 12.85 1st pass, 11.37@119 w/195 shot

Just plug it in, select tune car, then select custom tune, then select adjust options, you should adjust the saved options if it asks you. You will having timing adjustment and a bunch of other stuff. If it pings when you add timing make sure you pull it back out so you dont hurt the motor.

I don't mean to hijack or revive an old thread, but I have a custom tune as well and I wanted to adjust it but I was not sure how to know how much fuel%+/- i can take out, or what global timing is. I upped the global timing 4+ total and pulled 2% wot fuel out. It seems a little stronger down low but it may just be my imagination. Any ideas? I figured this would be better than starting a new thread because I know how people are about redundant threads on this forum.
Thanks in advance.
