You may need to add a little fuel with the predator,I added 10%.Custom tune is not necessary.I am investigating the option of installing a set of Kooks headers and a Corsa catback for my 2010 R/T and am wondering what the tuning implications are regarding the headers.
Ideal situation would be pop on the headers and catbacks and drive it without messing with tuning but something tells me this may not be the case. Given that there is a change in back pressure, what does this due to the stock setup and what if any changes in tuning are required - if there are any? Will the computer adjust or is it necessary for a custom tune.
Anybody have any insights on this?
