Dodge Challenger RT long tube headers w/Diablo tune

[provoc8r]

I've heard the Diablo 93 tune runs lean under normal driving, and rich at WOT. After the longtube header install, I was thinking about increasing fuel across the board by 5% to keep it from running too lean with the headers until I can get my custom tune. Will this cause it to run too rich at WOT?
I'll be installing tomorrow.
