Adding fuel when adding power?

So I have a predator with no custom tune as of yet. I just did the duals a few weeks ago. I figure I gained about 10 give or take rwhp. Would it be wise to add 1% fuel in the WOT Fuel setting to both the 2k-4k range and 4k-7k range? Thanks everyone!

You gained power because it's easier to push exhaust out, not because it's easier to pull air in. You don't need any extra fuel.

Ok, that makes sense. Thank you

Ugh, … the whole thing’s a working system, you can’t treat it as discrete pieces with zero interaction. Go and ahead and try the 1%, it won’t hurt anything. The worst that can happen is you’ll just change it back to where it is if it doesn’t run better.
