Pretty sure blue tops are not made anymore. Was a Ford injector or something. From the people I talked to who had them no one ever liked them. Depending on what your doing with the car guys have been into the low 11's with 009's. I used them for years and liked them allot. I turned up the boost a bit so I went with 50lbs. But the 009's are awesome street injector with a turbotweak chip.
