IS there a different ideal A/F ratio for turbo'd carburetor engines?

 

Um turbo is turbo no matter what motor you are boosting. You do not want a leave a/f when boosting as you can get away with with n/a . I try to stay mid to low 12's which is still kinda high for boost but thats me as a tuner. If you want to be safer shoot for 11's to keep your car together. I dont care about my car and want to make the most power hence the reason for me tuning a little lean.
