I just picked an 2002 Excursion. The truck has a 38R Garret turbo, intake, 4" stainless turbo back and bigger inner cooler "not sure of brand yet". It came with an SCT and i'm not sure what the programs that are on it. Who is someone that can help me out with this? I don't want anything crazy just want to utilize to the best benifit of the add on's. Trans was built by twisted diesel. Is their anything else mod wise i should do? Thanks for any help.
