How would I go about getting more performance out of my 2008 Saturn Vue?
Thus far I've had a 302 horsepower 5.4 liter Ford Expedition, a 188 horsepower 2.7 liter Suzuki Grand Vitara, and now a positively pathetic 215 horsepower 3.5 liter Saturn Vue (with the added insult that the 3.6 liter of my car's model year had 257 horsepower). Put simply, I'm sick of having a car with an engine that's roundly outperformed by every other engine on the road, including smaller (but still naturally aspirated) ones, and I've wanted to get experience working on cars anyway.
How should I go about getting some more oomph out of my Vue XE? I've been told that retuning it to run on premium gas would help power AND fuel economy (I currently get 16mpg), but I haven't a clue as to what kind of tuner to get for that, or if I'd be better off with some other performance enhancer.
I'm not asking for a miracle. Matching a 2015 Equinox's/Terrain's 301 horsepower isn't on my radar, let alone matching the output of tuned Equinoxes. I'd be happy with just 240 or 250 horsepower, preferably with better mileage than a 3/4 ton pickup truck.
