With reference to the pinging ... the superchip typically adds more spark advance which will cause pinging under certain conditions ... especially with lower octane fuel. I typically run 92 - 94 octane (best I can buy) and notice a vey light pinging sy around 2500 to 3000 RMP in 3rd as I accelerate. Nothing dramatic or destructive .. more of an annoyance than anything else.
I agree with the comments about waking up an ATX. I has a Superchip in my previous car (Mark VIII 4.6 V8) and it seemed the superchip made the upshifts faster, more positive, and also made the transmission more eager to unlock the torque converter and downshift when passing.
ALL-in-all a quality product and wothwhile addition IMHO.
