Been reading the sight on the Sprint Booster product and have some questions for folks that are currently using it, if you don't mind.


1- Does it make a noticeable difference? (seems to have mixed reviews)
2- Are you using it along with an ECU mod, any issues?
3- Given the Crossfire adjusts to your driving habits, how does the Sprint Booster accommodate for that?
4- What is the correct version to use with a manual transmission?
5- Any data supporting the Sprint Booster effects?

Thanks
