I was getting some pinging (or at least what I think is pinging) on the 87 tune with 87 gas. On this last tank, I filled up with 93 and went to the 93 tune, but I'm still getting the same noise... Maybe I should drop to the 91 tune and see what happens??? 
Any input would be most welcome!

You will be up against the knock sensors and it will retard the timing. Also, you run the risk of pre-detonation.
With as much as SC pushes things to get you the best performance, this is not at all advisable. If it were closer in octane, and it was running fine, say the 91 tune with 89 Octane I wouldn't be as concerned. However running the 93 tune on 87 is just asking for trouble.

I switched to the 87 tune last night with 87 fuel and it runs great! I no longer have to put the pedal to the floor to get the JK to start moving.

Just ran it. Very noticable when you let the clutch out, no more 'about to stall' issues. The ecceleration is noticably better. I only drove it for 1/4 mile is all. I will put some 91 in it tomarrow and run it more. I know the intake and exhaust will enhance the Superchip even more. All i did was the 93 tune and tire size. I run 35's and i set the program to 33.5 as some have done. I will GPS it and see. The only real way to tell the difference in power is to drive it in the 93 for a week, then set it back to stock.

I suggest everyone go back to stock after driving on a superchips tune for a few weeks just to see how big the difference is.

It's funny you say that. When I got my superchips I was impressed. But a couple months later I set it back to stock to take it into the dealer. Wow what a noticeable difference. It felt like I was running on 5 cylinders.

Cai ?
just installed a AEM CAI and have a noticeable performance loss. I had the superchip tuned to an 87 tune before the CAI install and had good performance. After the CAI install it started pinging and was a total dog. MPG went to crap too, 1/4 tank in about 70 miles.
last night i went back to the stock tune and it seemed like it actually ran better. Any ideas?
