I don't have much experience with mass air. Does my tune have to change when I put the blower on? If the meter measures the amount of air passing through it, then shouldn't it automatically add the fuel for the amount of air? I just want to be prepared before I put it on.
Thanks!

Re: Going supercharged, what needs to change
If the MAF measures the air, it'll match that. But what you do have to deal with is the fact that the stock tune tops out at 75-80% load. But with a boosted application, you'll go well into the 120-150% load if not higher depending on your level of boost. So you'll need to rescale your various tables to accommodate boost levels that high.
