Gains With Only a Tune?
I read the thread about the Soler Throttle Body, wherein the OP said the car's computer was basically shutting down the ability to make power with the throttle body, due to the stock tune.
I'm wondering how much power can be had by simply tuning a stock engine, or one with a throttle body, or an exhaust, or a CAI. These components don't really seem to add power, but are pretty common.
Would there be any negatives to going this route? Could a person get 50-70 HP just letting the engine realize the full potential of a basically stock set-up?
Curious minds want to know............
PS: Also, when a car is tuned, how does it still pass emissions tests?
