im looking at getting the turbo xs utech. What one do u recomend and how much power will i get from it.

 

depending on where you are i would get a ecutek if you have a tuner near you. Or the other great option is a cobb accessport if you arnt close to a tuner. You will receive a good amount of power with the safety of your stock ecu...meaning it will make changes for elevation or heat. It is a much better idea for your mods as of now.
