Installed headers on '10 Chall, Adjust fuel mapping to what?

[aarcuda72032]

Like I said, I installed long tube headers on my 2010 Challenger. has anyone done any AF ratio logging with their cars after installing LT headers (this is a 5.7 RT) and figured out how much fuel to add to keep it down in the 12.5 to 12.9 AF range??

I dont have my wideband hooked up yet so any info from others would be a good baseline for me

Start by adding 10%.
