I don't know what's going on with your truck, but the calibration is correct and similar to the other lope idle tunes that we sell for different PCM codes. How does the 120 lope compare to the 120R program you have?
The biggest "contributor" to how well the lope works is the condition of the IPR and the PCM's response to ICP changes.
