A little background...I have 2400 miles on my '13 truck. I towed my trailer a little over a month ago about 700 miles round trip when my truck was completely stock. On that trip the truck ran perfect...not so much as a hick up.
Since then I have upgraded the exhaust, CAI and tune (see signature for details). Yesterday while towing my trailer on a 100 mile trip, the engine began making a loud, and abnormal sound about every 3-5 minutes (not sure how to describe it other than it sounded like it was related to the turbos). I was driving 65 mph into a strong headwind. The truck didn't loose power and the gauges were normal so I kept driving assuming that it was due to the strong headwinds. After about 20 minutes it made the same sound three times within about 60 seconds. After the last one, the truck lost power and the CEL came on.
I pulled onto the shoulder and shut it down. At this point I'm pretty pissed because I was about 50 miles from home with a broke truck and no way to get my trailer home. I checked under the hood and under the truck. Everything looked normal (no leaks, etc) to me in my very limited knowledge of what an engine is suppose to look like. I restarted the truck and the CEL was gone and the truck was running normal. I revved the engine a few times and it sounded normal. Put it in gear to see if it would move and it accelerated normally.
Being that I was half way between my home and my destination, I had to decide whether to turn back or continue. As I was traveling down the highway at 65 mph to the next exit, the truck was running normally again. No strange noises, no CEL. SO...I decided to go ahead and continue the trip and if the problem happens again, I would head to the nearest dealership.
I completed the trip with no more problems. Once I got the trailer setup, I used my SCT tuner to read codes. It shows no trouble codes. I thought that was strange since the CEL did turn on.
I don't know much about engines, but I know this truck ran/towed perfectly when stock. After the upgrades, I have problems towing...so...I have to assume either the tune, exhaust or CAI have caused the problem. Anyone else have a similar experience?
By the way, I am running the canned 87 octane SCT tune.
Thanks in advance for any help or suggestions.
