You'll need to start by inputting the correct injector data and pull about 5 degrees of timing from .6 airmass and up. Dial in fueling then timing.

Do I need to upgrade to a 2bar os for 7-8psi boost?
do i need to use the original maf sensor or the increased performance? Or even turn it off?
???

Your previous question isn’t really clear.
Most boosted vehicles are tuned In speed density without a MAF. In some occasions i believe there is some that have MAF but they are running very little boost.
Whether to tune with or without the MAF is a larger question I'm not qualified to answer. But I don't think it matters which MAF you use, it just needs to be scaled correctly. I would stick with the one that is stock with your ECM.
how to correctly complete this table with 42lb injectors 17113739? Do I need a fuel pressure vacuum control line?Безымянный.jpg
The g/s symbol - click on it and change it to lb/hr. Also you REALLY REALLY need all of the injector data for it to be right. Otherwise you'll chase your tail a lot. 42lb doesn't sound right if that's what came with the blower. Would think they would be bigger?

I remember the early days of the mp112 blowers for the trucks they only come with the 8.1 marine injectors.
I checked them by number and tested them on the injector test stand. they are 42lb.
