I have had my deletes done now for about a 1 1/2 years now. This weekend I went pulling and pulled in 2 classes. The truck did great. Won the first class and got 7th in the other which I was still happy with considering there are some heavy hitters in that class. Any way truck ran good like I said but it smoked like a train the whole way down the track. I think alot of the smoke was from the water/methanol 50/50. When I pulled off the track after the second pull it had a little miss in the idle. Actually sound like it was looping. So let it run for a little bit then shut it down, then went to leave and still had the miss at idle. Drove it home and it seem to run fine but my engine brake didn't work. Then my CEL came on, so I pulled over to check it and it was the P2262. I thought I would never see that one again. Well got home and the next mourning went out to check out the truck and now the miss was bad at idle and even at driving, and now it was blowing out bluish smoke. Thought it was an injector but the dealer says its the turbo. The turbo seems to spin up just fine and doesn't make any werid noises, just the engine brake doesn't work. Can't beleive they want to put on a trubo and not even trouble shoot it. Well has anybody had anything similar with their trucks or heard of any trouble with the stock turbo after the delets?
