remove, yank, rip, take-out.... It's all the same. Before you go out rolling your eyes everywhere maybe you should use them to read some theory of fluid dynamics. Or if you understood the reactions that take place when you remove the screen you would undestand that just like I said, there is no way to "program" for the Descreen. Other then "minimal" flow increese most people will target a slightly more rich mixture since it's extremely common to suffer from a lean condition after words. Again, once you understand it's reason for being there, the rest will make sence. A tuner can't just say. "oh, well his MAF is descreened, I'll just change xx x x x to x x x x x and it will be perfect". But go ahead, ask why tuners recomend NOT changing the MAF and why they don't like to try to tune around a non stock MAF and see what happens. So as I said. You can not "tune" for the MAF descreen. But they wil try to adjust The tune to prevent damadge... If it was up to bryan, Ion, or any other tuner there would be no descreening or aftermarket MAF's. It would make life for them a lot easier.
