2 out of 5 stars review
My car ran well before
I have called Holley Tech line several times regarding my stock GM Injectors no being available in the Holley software menu. I googled my injectors and found several Holley forums with people with the same issue dated all the back to 2015. I should've kept my stock stuff.
