Yep. No amount of computer changes are going to net more than 15-20
horsepower without hardware changes, i.e., intake manifold, exhaust
manifold, cylinder heads, etc. Unless you have computer controlled valve
timing (the northstar motor supposedly has this, but i havent seen it).
You can continue to add fuel and spark advance to a car with the
computer, but until there is more air and more turbulence to match that
fuel, and less resistance to evacuate it, you are going to make small
gains in power. Oh, this does not of course apply to forced induction
vehicles.

This isnt particularly unusual; The Dodge Neon tops out first gear at
64mph. (automatic) Your car probably is similar.

As indicated by the speedometer, or calculated by gearing/rpm/tire
circumference? Depending on the weight of the car and the coefficient of
drag, it is ... unlikely you were actually exceeding 160mph with a
sub-300hp engine. Furthermore, unless you had VR or ZR tires on the car,
traveling in excess of 154mph for any length of period is likely to
explode one or all of your tires.
