theres a local guy for me in South NJ, website is:
https://injector-rehab.com/product/b...-flow-testing/
i sent my stock injectors there. had all the service done. provides a nice test report/etc. and i wound up selling them on ebay. i think i still have 3 left out of the 8.
i figured i spent insane money on the rebuild, and i really wanted new injectors.
