how can i increase the vaccum of air by using the predator
Advancing spark timing usually gets you nothing but spark knock unless you understand what you are doing. As for the vacuum of air question, I think what you mean and want is for the car to breath better. This won't be done with the predator; you need to replace your intake and exhaust parts with better performing components for that. The predator has built in tune(s) to optimize your performance. You simply select the diablo tune for this. The option to adjust a tune requires you to know what you are doing and isn't designed for guess work. Diablosport has a technical forum where you can ask some questions that might lead to helping you get what you want.
