Alright so Im going through this dispute of what injector size I should go with. Should I go with the 42s or the 60s? Now I will have a forced induction set up. At the moment I dont plan on running e85. For now I just plan on getting the car running decently. Once things settle in I will plan to swap to e85. Now my question is can I run 60s with 91 octane and use the 60s at a lower percentage? Or is there a specific operating range for the the injectors.

Thanks in advance!
