i know on my 2009 RT, I run the 91 tune, with 93 oct gas. I have a trinity if that makes a difference , but last time I had mine dyno'd. it pulled more RWHP and Torque with the 91 than the 93. so I run the 91 tune all the time. if and when i go to the track, i just adjust some of the perimeters on that 91 tune and when I finish I go back to the 91 adjustments I had before.
didnt really notice any bogging off line, with the Nitto drag radials, I would get a lot of spin though, took a while to get them to hook, but with the M&H drag radials, they would hook right away. the 91 just seemed better to run and got better runs from it.
