yours should be ok. As I understand from the great guys on this forum you shouldn't need the relearn as your solenoid is still the same. I need the relearn as I replaced my turbo with a reman from BD diesel ( they machine out some of the problem areas). The cleaning only lasts so long and the antiseize doesn't really work. hi temp antiseize is only good to 900 degrees and the exhaust temps hit 1200. Just burns it off. After taking mine apart I would say the cleaning would last different lengths for different guys depending on how bad your turbo is. Mine was full of rust and pitting. I couldn't get back to the original finish that would repel carbon and rust better. rusty surface will always re-rust much faster than the first time. I replaced mine as I figured I would be taking it back apart again within a fairly short amount of time. Not worth it if I am going to have to buy a new one anyways.
as far as the relearn I got this from another post on this site:
KAM (keep-alive-memory) reset & VGT learn procedure
1. Drive the truck until the engine and transmission have reached normal operating temperature.
(The VGT learn procedure requires that the oil and coolant temperatures be at normal operating temperature)
2. Flash truck back to stock (Only need to do this if running a tuner or module)
3. Turn on the headlights
4. Disconnect both batteries
5. Short out + to - battery cables to each other (Make sure both batteries are disconnected before doing this).
6. Let truck sit like this for 10-minutes
7. Turn off the headlights.
8. Re-connect batteries
9. Cycle the key to the run position twice. Pause in the “ON” position each time until the wait to start lamp goes out (minimum 5-seconds) and pause in the “OFF” position each time for 10-seconds to be sure the PCM has "gone to sleep".
10. Start the truck and let it idle for a minimum of 5-minutes at normal operating temperature. This allows the PCM to learn the EGR valve closed position value. Also you will likely hear the turbo pitch change several times during this period as the PCM learns the necessary duty cycles for accurate VGT control.
11. Complete the road test Drive Cycle:
15 miles of mixed driving (*should* be enough in most cases) to allow the PCM to "re-learn" its adaptive strategy.
Note: Anytime the batteries are disconnected, the PCM will throw the P1000 code until the “Drive Cycle” is completed.
As for the Tow/Haul mode, the transmission must re-learn your driving style and loads hauled again as this was cleared when the truck was re-flashed.
gonna go and try it right now
Hope it helps
