no such setting, each car is different and requires different duty cycle

ps it would help if we knew boost controller so someone can guide u towards that mark

Yes and what duty cycle are you trying to tune?

If its your boost controllers duty cycle (which is what I am assuming based on your posts) you will need to monitor your boost delivery and adjust the controller accordingly.

If it is spiking you will want to turn the duty down. If that takes your target boost down then turn ur target boost back up. Fiddle with the two until you get the happy medium you are after.

If it is your injector duty, you really need a wideband AFR and a good knowledge of tuning to be able to adust this. There is no 'good setting' you can simply apply and use.
