Obviously I'm new to this and have a couple basic questions about the boost tables. First, what does the x-axis represent (columns ranging from 526 to 1000 across the top of the table)? Also, why are there multiple columns on the x-axis at the far right that are 1000? They all have the same pressure values down the column, but not sure what the purpose is to have several of the same columns in the table. Thanks in advance for anyone who is willing to help out with some dumb questions...

That's atmospheric pressure.

You'd have to ask the Honda engineers why they used so many repeat values instead of just making the table smaller.
