Ok so my 07 supercrew 2wd 5.4 runs fine...but i just did a level 20's and 35x12.5's. And cruising around town its fine but when i get in highway every hill shes kickin down a gear or 2. Would a programmer fix this issue or am i stuck with it shifting constantly? Heres a pic if truck
Yea rough country 2.5" level in front w 1" blocks in rear w new shocks from rough country also. It rubs a little when in a parking lot but thats bc of my wheel spacing. Ive already done cop boots. Need to do plugs but im scared lol
Dont be scared of the plugs, I had the Lisle tool on hand, removed the plugs after the engine warmed up and broke none at 113K. I did run a full bottle of Seafoam through the gas tank for 200 miles before hand to help break up some carbon.
