[Shotimes] 7000RPM, Man , I'd have to spin a bearing

[Paul Nimz]

I am testing a new chip for my '97.  One of the things I asked for is a
higher speed that I can downshift from 2-1.  OEM is ~15 mph.  Absolutely
useless.  The chip I have now lets me downshift it at 35 mph on a closed
throttle.  Excellent IMHO.
