Any tuner can make "amazing results" on a factory turbo car. All you have to do is turn up the boost.
Tuning a naturally aspirated engine is a whole other ballgame, and 9hp is actually a very respectable gain from a reflash of a 3.7L NA motor. Also keep in mind that our motors are tuned pretty well from the factory.
And the amount of power you can get from a tune is going to vary wildly depending on the specific vehicle, what mods are on it, what shape the engine is in, etc. If some mods were done which cause the car to run extra rich, then leaning it back out to optimum AFR will get you some good gains. If some combination of mods already leaned out the engine to dangerous levels, the AFR will need to be richened to keep it safe, possibly even at the cost of some power.
