Superchips was the way to go for me.
I got a Flip Chip.
Its a dual program chip.
One program is for everyday driving and the other program is for running nitrous.
Sent in a dyno plot of my car and the everyday program was "custom" tuned for my ECU code.
They also tuned the everday driving program for colder plugs (because I'll be running nitrous and have to have the colder plugs) and 92 octane gas.
Total cost was a bit over $600.
Was worth every penny!
