I bought a 08 that's deleted with the small efi box and harness in the glove box from hardway. The old guy I bought it from had a shop do the work and didnt know anything about it. The truck runs awesome but you have to be carefull about being rude with the smoke, I've been turning down the tunes one day at a time and now running it on stock and it runs the exact same. I have a dtc code of ecm po11 also. Just want to make sure I'm not doing something wrong on my end before I call in again. Thanks Jason
2008 with efi not able to change tunes

No switch just obd port, it has 5 preset tunes 1stock 2tow 3, 4, and 5. I called in to hardway and they walked me through the procedure on the phone and I first went down to the 3 setting (street), then to 2 (tow) without any difference. I'm now on 1 (stock) and it runs the exact same, smokes like hell over half throttle.

Some of these Goons love a good smokey tune? May need to send the tunes to Hardway to make sure what the tunes are.
Verify that code, that may be the main reason?
P0011 A Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)
P0110 Intake Air Temperature Circuit Malfunction
P0111 Intake Air Temperature Circuit Range/Performance Problem
if it is a P 0011 that is a code I've never seen.

P0111-INTAKE AIR TEMPERATURE (IAT) SENSOR RATIONALITY
For a complete wiring diagram Refer to Section 8W.
When Monitored:
While the engine is running.
Set Condition:
The ECM does not read a change in value from the sensor over time.
Possible Causes
FAILED IAT SENSOR
INTERMITTENT CONDITION
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)
Diagnostic Test
1. FAILED IAT SENSOR
--------------------------------------------------------------------------------
Remove the temperature sensor and reconnect the wiring to the sensor. Monitor scan tool, while heating the sensor with an external heat source (DO NOT USE OPEN FLAME).
Does the reading from the sensor increase at least 5 degrees F. on the scan tool?
Yes
Refer to the INTERMITTENT CONDITION Symptom (Diagnostic Procedure). (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL). (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/ENGINE CONTROL MODULE - DIAGNOSIS AND TESTING)
No
Replace the Intake air temp sensor/MAP sensor.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL). (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/ENGINE CONTROL MODULE - DIAGNOSIS AND TESTING)
