unless you drive a 99 silverado, your stock injectors will take you a LONG way. do you know what your IDC is at?

I'm sure what my idc is at but I wan't to upgrade as a precaution. I'm looking to spray in the future. And i might as well upgrade while I do my cam and tune this spring.


thanks for all the help guy's.
