2010 WK 5.7L
Catch can, drop in K&N
I run the recommended 89 fuel but just wondering which would be a better choice to run form my predator? the 87 or 91 perf tune? It feels like I am getting more performance from the 91, but just wondering if there would be any negative effects like long term damage.
Thank you

You should only run the 87 tune with that fuel, unless you are logging for knock to make sure its all safe.
