So I have a 97 expedition with a 5.4 swap. I got the truck with the swap done and it was all jack up. After a bunch of sensors reconected and etc I put money in to geting tunes done. Before my tunes came in I ran the cann tow tune for a 4.6 on the truck and it would run pretty good but it was missing power for a 350ftlb motor. After the tunes man o man did it come to life, I have pulled a few small things with the new tow tune and theres a big differance there plus the 87 performance tune is nice for spinning the 315 with a crack of the throttle
Thanks Bill its the best money spent by far
