2015 Ram 85,000 miles all stock.
7 days ago Saturday: I added a SFT ECM tuner. Copied TCM original file. Everything runs great. Put maybe 20 miles on truck.
Sunday: Didn't drive truck.
Monday: Drove to work 80 miles round trip. Emailed SFT the TCM file. Truck drove great. Already seeing the fuel mileage increase.
Tuesday: Drove to work 80 miles round trip. I receive tuned TCM file. Loaded new file. Truck drives even better. Removed EGR tube and installed blocking plates and connected a CCV catch can during lunch break. Drove home.
Wednesday: Drove to work 80 miles round trip. Also went to a test field 45 miles round trip. Truck drove great but coworker following me said they saw some white smoke come out off exhaust when leaving red lights.
Thursday: Drive to work. 40 miles. Coming home from work cruise is set at 72 mph and I am coming up a hill. I hear a sound like an intake boot has blew off, the truck starts losing power and Service Electronic Throttle Control message comes up. I am at my exit so I get off highway and pull into parking lot. I leave the truck running and open hood to look for hose blown off. I can't find anything wrong. Scared to shut it off, I drive the rest of the way home. 25 miles. Truck sounds fine at idle and has power until about 1500 to 1600 rpm then just falls on it's face. Max rpms I could get was 3000. You can hear the turbo spool up but it feels like you have half power.
At Home:
I take out the MAP sensor and clean with CRC electronic parts cleaner. It was dirty. No change.
I check MAF sensor wiring and grid. Seems OK.
I reinstall EGR tube and disconnect CCV catch can. Reinstall original ECM and TCM files. Start engine. Warning light is gone. OK maybe good now. Go for test drive.
Worse now. The truck stumbles, misfires and bucks the whole truck. If you keep foot on the gas, it finally smoothed up, turbo spooled and took off for about 2 seconds then the Service Electronic Throttle Control message comes on again with a P0299 check engine light. P0299 is Turbo low boost. I limp back to the house and park.
Now I need some advice on what to check or what to do.
Sorry for the long post.
Thanks in advance.
