Suppose to be the best pcm for the 99-01 maybe 02-03s with manual trans. I had my truck dynod this past weekend and I wanted to swap in this pcm and try it again this weekend along with a few other tweaks to see if it made a difference. And DI did my tuning and he said that my chip was tuned for a dac3
00 f250 some stuff done always more to do.
Best advice I have seen on here "If you cant afford to build it right you certainly cant afford to build it twice"
