ive looked all over and can’t find a post that explains how to do this

I have Bosch 650cc injectors that I haven’t put in my car yet and I’m trying to figure how to tune for them with dsmlink v3 after I have them in

Can someone explain how to do it?
 
This should explain it.......basically, if you run twice as much injector than stock, you need to decrease fuel delivery by half, so 900cc injectors need a global fuel adjustment of -50%. Stock are 450cc except auto 1g cars which are 390cc. You are telling the cars computer to reduce its fuel delivery in half, for that example.
675cc would require -25%
1350cc, -75%
Or you can read it all here.....

450(stock)/size of injector(650 in your example) -1 >> 450/650 -1 = -30.7 or thereabouts for your global fuel in link, you should also have a data sheet that came with you injectors which tells you what voltage to input in link..
