yep, heard about that. almost makes it worth it having a tuned and stock ecu programmed to the same rig anf just swapping em outWhat makes it worse, they now check the ECU checksums to insure that what ever is loaded.. or has been loaded in the past.. has not changed the ECU. You can be forced to go to the dealership for a firmware flash update and get the card from the dealership saying it has been done. This happened to me with my JKUR - a forced emissions recall on the ECU had to be performed to renew the vehicle license.
Ehhh...but at least the ranger is good on gas but yeah, have thought that too!
I installed everything but the muffler last weekend. New plugs, k&n, and the programer. The truck is much lighter on it's feet, and when you get it in it's peak power bad at 4500rpm, it comes on like a bat out of hell. Even on 34's it's pretty quick once it gets moving.
The real surprise has been gas mileage. Before I was in the low 17mpg. Now I'm at 20mpg.
In 10th gear, at 70mph she is only around 1500rpm.
Pretty happy with the results so far.
