I run 65%sacs with lbz pump ml converter korys tuning. 369 .91ar. My truck rips hard I tow with it also just needed to install tap shifter tho bc below 1900rpm truck dogs out. I gross 23k sometimes and long hills you got to make sure your in right gear. I did run it with 100% overs Voc and 10mm pump no change in performance other then pulse width is little higher and hazing has been cut down. Currently over 18k on this turbo. Shitty prt is no replacement wheel yet and mine does have some nicks in it.. Not sure how but there there. Turbo is still tight tho
