    What are you using to control fuel? I wouldn't really try much more than 24 on motronic, and if you're using a standalone like megasquirt, you may as well go for something bigger, like 42 lb injectors. They're not much more expensive, and they'll give you the option for more boost.

        19# are too small for any level of boost, anyway.
