Default PFC settings when changing 440's to 550's

Am I right that I change the injector settings from 100% to 80% to stay on my current map?

It's a safe base map until it gets mapped properly.

85% probably closer but I would stay off boost as they arent always equal flow across the whole map

Cheers Simon!

I'm going to fit them a week or so before the mapping session and drive the car to make sure there are no issues with the engine I have fitted. I have a safe map loaded into the pfc but will keep off boost as you say.

As soon as I get some test on it I will give you a call to get it mapped. I was no where near in August this year.
