replacing PCM?

received a new flashed PCM from DP Tuner this morning, any quick instructions out there for replacing this thing? I have seen something somewhere, can't remember.

Loosen a bolt on the firewall inside the engine bay then a few nuts underneath from the front and it should just slide on out correct?

Pretty basic. I believe you've got it down. Many have done this without disconnecting the battery cables first. But, I leave that up to you. Better safe than sorry.

What Mike said is very important. Put the keys on your work bench.

heh, left the keys in the house, finished this about 30 min ago, just got back from a test drive....


HOLY CRAP

mileage just kept wanting to go up (got the 80E) and power was incredible when I wanted to put my foot down, shifts better, drives better in every way....

totally different truck in every way, this is so awesome! I can't imagine what 140 would do, that would just be nutty

heh, I don't doubt it lol, that is just to fun!

unfortunately I have an 88 mile round trip commute that I have to do 1-3 times per week, I keep it at 65, been getting about 16-18 mpg (depends on how much in town crap goes on during that time) I am hoping for some really good things here!

hell it was worth it just for the fun factor
