So I am new to the sho but not new to cars. Better with the 6.7l diesel. So that being said going to pick up a stock 1 owner 2015 today what's songs of the first things to get great gas mileage and make the car better all around. P.s. pretty good with the 3.5l non turbo have 3 of them in different cars plus extra 2014 3.5l non turbo with 10,000 on it sitting waiting for a complete built up to drop in the sho in the future. Thanks for any advice.
