But since the 87 custom tune is not faster than the 93 canned tune, I am in the process of editing the 87 custom to my standards.
Right now I only advanced timing to 1.5, of course using 93 gas.
Tomorrow I will be advancing it to 2 and maybe mess with the spark

One question, if I am editing the custom tune, the other values of the custom tune will be the same correct?
I m asking this because when I have the 87 custom tune loaded, it idles at around 600-650.
But when I edit the custom tune, it is not at 500 idle

Good luck!
I would rather goto the master and have him change it then to do what you're doing.
Maybe there's a reason why he wrote your tune the way he did............
