I am not trying to stir a hornets nest, but in all my research, I have NEVER heard of anyone getting a measureable gain from injectors. I have also read in numerous places our stock injectors are good to something like 350HP, so unless you are FI, you probably will not lean out.
Please correct me if I am wrong, I just want the correct info for myself and others on the forum and I see injectors being brought up an awful lot lately from newer members. I know they actually hurt performance on one members car here who was modded and he put his back to OEM....
