AFAIK their is no way to get the active calibration off of the ECM so you definately need to get the dealer to give you a copy.

#25, #27 etc. refers to the calibrationnumber. If you look at the tables listing all the calibration files it is the second column in the table.

 

try a squirt bottle of water next time you start it.
Squirt it around the intake seals.
If you have leak there it will seal it and idle should drop off,

 

choochoo, I,ll try the water trick. They just replaced the seals the second time last Thursday. After looking at how they are made, why cant a person use a large viton O ring of the proper size and use Bellville spring washer and nylock locknut to maintain some pressure on the sealing surface. I don,t have access to a old head and intake to play with to see if it is plausible.
