Back on August 20, 2011 I cleaned my MAP sensor, at 52,605 miles. At the same time I performed the ORM. My sensor looked every bit as crusty as the ones in SirSam's noob guide (viewtopic.php?f=5&t=54207) and OLD NAVY's tech report (viewtopic.php?f=98&t=22630). I don't know if it had ever been cleaned before, I am not the original owner, but I doubt it.

One month later, September 24, 2011, with 55,031 miles, I installed the GDE HOT tune and undid the ORM.

Hadn't touched the MAP sensor since then.

Yesterday (January 21, 2013) I decided to clean it again, since it's been a while. The Jeep now has 73,274 miles on it. went out and was pleasantly surprised, this is the unretouched photo of what it looked like BEFORE cleaning.



I do not have a provent, EHM, or anything else. So I am a true believer it the GDE tunes for more than just the power and fuel economy.

Kudos to Green Diesel Engineering.

GDE full torque here for 35k miles with clear clean oil all the way to 5k miles, and if I may add. I have the f37 TC, and believe it or not, I have not even have shrudders.

Like I said in the past, the oil going through the intake would remove the carbon build up from pre tune, it looks like the CCV oil is doing a good job cleaning things up. I wont be pulling my MAP until an OBD scans says it is bad.
