Dyno day at Apex would be great! I dyno'ed my SHO there and it let me know just how out of whack it was (which made me sell it).
For the ATX... a superchip is a nice addition as I had it with in my Mystique. I do not think the car had any more power (once I was modified) but it helped out. 1-2 MPG increase and the shift points are mapped much better. It would actually go to the 6950 rpm redline for each shift. You could get the same by manually shifting it though. Really firmed it up especially part throttle shifts.
Best bet with an ATX is to protect the trans, a shift kit and some good synthetic ATF will do wonders especially when mated with a chip.
Racing my ATX at the track never netted good times. I think a 17.2 was my best
highway runs are where the car would shine. If you are to run it make sure you have the proper size tires and stock wheels. My 17" Konigs and low profile tires did nothing but hurt times. The car was much much faster with the stock 15" rims and less traction!
